Filters
Filter objects intercept requests and responses during processing, and change them as follows:
-
Leave the request, response, and contexts unchanged. For example, the filter can simply can log the context as it passes through the filter.
-
In the request flow, change any aspect of the request (such as the URL, headers, or entity), or replace the request with a new Request object.
-
In the response flow, change any aspect of the response (such as the status, headers, or entity), or return a new Response instance
AllowOnlyFilter
Authorizes a request to continue processing if it satisfies at least one of the configured rules. Otherwise, passes the request to the FailureHandler or returns an HTTP 401 Unauthorized, with an empty response body.
This filter manages requests from the last request sender, otherwise called the request from the last hop, or the request from a direct client.
For debugging, configure the AllowOnlyFilter name
, and add the following
logger to logback.xml
, replacing filter_name with
the name:
org.forgerock.openig.filter.allow.AllowOnlyFilter.filter_name
For more information, see Managing logs.

Examples
In the following example, a request is authorized if the last request sender satisfies either of the following conditions:
-
Certificate subjectDN matches
.*CN=test$
orCN=me
, and the IP address is in the range 1.2.3.0/24. -
IP address is 123.43.56.8.
"from": [
{
"certificate": {
"subjectDNs": [".*CN=test$", "CN=me"]
},
"ip": {
"list": ["1.2.3.0/24"]
}
},
{
"ip": {
"list": ["123.43.56.8"]
}
},
]
In the following example, a request is authorized if the request destination satisfies all of the following conditions:
-
The host is
myhost1.com
orwww.myhost1.com
-
The port is
80
. -
The method is
POST
orGET
-
The path matches
/user/*
.
"destination": [
{
"hosts": ["myhost1.com", "www.myhost1.com"],
"ports": ["80"],
"methods": ["POST", "GET"],
"paths": ["/user/*"]

The following example authorizes a request to continue processing if the
requests meets the conditions set by either rule1
or rule2
:
{
"type": "AllowOnlyFilter",
"config": {
"rules": [
{
"name": "rule1",

}
}
AmSessionIdleTimeoutFilter
Forces the revocation of AM sessions that have been idle for a specified duration. The AmSessionIdleTimeoutFilter issues an authenticated and encrypted JWT to track activity on the AM session, and conveys it within a persistent cookie. The tracking token contains the following parts:
-
The time when the user was last active
-
A hash of the AM session cookie, to bind the tracking token to the AM session cookie
-
The idle timeout
Multiple filter instances can share the same tracking token, for example, in a clustered IG configuration, or when a federation of applications protected by authentication filters need to have a flexible idle timeout strategy.
AmSessionIdleTimeoutFilter requires the following configuration:
-
In AM, client-side sessions must be enabled for the realm in which the tracking token operates. See Configure client-side sessions in AM’s Sessions Guide.
-
In AM, client-side session denylisting must be enabled. See Configure client-side session denylisting in AM’s Sessions Guide.
-
The AmSessionIdleTimeoutFilter must be placed in a route before a filter that uses the AM session token, such as a SingleSignOnFilter or PolicyEnforcementFilter.
-
In production environments, and when multiple AmSessionIdleTimeoutFilters use the same tracking token, the encryption must not rely on the default configuration. It must be configured identically on each filter that uses the tracking token.
The following image shows the flow of information when an AmSessionIdleTimeoutFilter sits in front of a CrossDomainSingleSignOnFilter, to manage AM session timeout.
[1-5] When the AmSessionIdleTimeoutFilter receives an unauthenticated request, it passes the request along the chain, and the CrossDomainSingleSignOnFilter manages authentication.
[6-8] When the AmSessionIdleTimeoutFilter receives an authenticated request, it checks that the AM session token is valid, and then passes the request along the chain.
[9-10] If the AM session was valid, the AmSessionIdleTimeoutFilter issues a tracking token on the response flow, containing the following information:
-
Hash of the AM session token
-
Current timestamp
-
Idle timeout of the current filter
If the AM session was not valid, the AmSessionIdleTimeoutFilter does nothing on the response flow.
[11-12] The AmSessionIdleTimeoutFilter places the tracking token in persistent tracking cookie, and sends it with the response, to be used in the next request.
[13-15] When the same or another AmSessionIdleTimeoutFilter receives an authenticated request with a tracking token, it checks that the AM session token is valid, and checks that tracking token hash is bound to the AM session.
[16] Depending on the strategy set by idleTimeoutUpdate
, the
AmSessionIdleTimeoutFilter selects the value for idleTimeout
from the tracking
token (set by the AmSessionIdleTimeoutFilter in a previous request) or from
its own value of idleTimeout
(if this is a different instance of
AmSessionIdleTimeoutFilter).
The AmSessionIdleTimeoutFilter checks for AM session timeout. If the last activity time plus the idle timeout is before the current time, the session has timed out. For example, a session with the following values has timed out:
-
last activity time: 15h30 today
-
idle timeout: 5 mins
-
current time: 15h40
[17-21] The AM session has timed out, so the AmSessionIdleTimeoutFilter does the following:
-
Forces AM to revoke the session.
-
Passes the request along the chain.
-
Expires the tracking cookie on the response flow, and sends it with the response.
[22-26] The session has not timed out, so the AmSessionIdleTimeoutFilter does the following:
-
Passes the request along the chain.
-
Updates the tracking token on the response flow, with the current timestamp and the value for
idleTimeOut
, using the same value for that was selected in step 16. -
Places the tracking token in a persistent tracking cookie, and sends it with the response, to be used in the next request.

The AmService that refers to the AM instance that issue tracked session token.
"idleTimeout"
: configuration expression<duration>, required-
The time a session can be inactive before it is considered as idle.
When an AmSessionIdleTimeoutFilter creates the tracking token, the token’s value for
idleTimeout
is set by this property. When a different AmSessionIdleTimeoutFilter accesses the same tracking token, depending on the strategy set byidleTimeoutUpdate
, the token’s value foridleTimeout
can be updated by the second AmSessionIdleTimeoutFilter. "sessionToken"
: runtime expression<string>, optional-
The location of the AM session token in the request. The following example accesses the first value of the request cookie
iPlanetDirectoryPro
:"sessionToken": "${request.cookies['iPlanetDirectoryPro'][0].value}"
For more information, refer to Find the AM session cookie name.
Default:
${request.cookies['<cookie name defined in the referenced AmService>'][0].value}
idleTimeoutUpdate
: configuration expression<enumeration>, required-
When multiple AmSessionIdleTimeoutFilters use the same tracking token, this property selects whether to use the
idleTimeout
from this filter or from the tracking token.Use one of the following values:
-
NEVER
: Use the idle timeout from the tracking token, and ignore the idle timeout from this filter. -
ALWAYS
: Use the idle timeout from this filter, and ignore the idle timeout from the tracking token. -
INCREASE_ONLY
: Compare the idle timeout from this filter and the tracking token, and use the longest value. -

: SecretsProvider reference, optional-
The SecretsProvider to query for secrets to encrypt the tracking token.
"encryptionSecretId"
: configuration expression<secret-id>, optional-
The secret ID of the encryption key used to encrypt the tracking cookie.

Authenticated encryption is achieved with a symmetric encryption key. Therefore, the secret must refer to a symmetric key.
For more information, refer to RFC 5116.
Default: When no
secretsProvider
is provides, IG generates a random symmetric key for authenticated encryption.

LAX
: Send the cookie only with GET requests in a first-party context, where the URL in the address bar matches the cookie domain. Not case-sensitive. Use this value to reduce the risk of cross-site request forgery (CSRF) attacks. -
NONE
: Send the cookie whenever a request is made to the cookie domain. With this setting, consider settingsecure
totrue
to prevent browsers from rejecting the cookie. For more information, refer to SameSite cookies.
Default: Null
-
"secure"
: configuration expression<boolean>, optional-
Flag to limit the scope of the cookie to secure channels.

AssignmentFilter
Verifies that a specified condition is met. If the condition is met or if no condition is specified, the value is assigned to the target. Values can be assigned before the request is handled and after the response is handled.
Usage
{
"name": string,
"type": "AssignmentFilter",
"config": {
"onRequest": [
{
"condition": runtime expression<boolean>,
"target": lvalue-expression,
"value": runtime expression
}, ...
],
"onResponse": [
{
"condition": runtime expression<boolean>,
"target": lvalue-expression,
"value": runtime expression
}, ...
]
}
}
Properties
"onRequest"
: array of objects, optional-
Defines a list of assignment bindings to evaluate before the request is handled.
"onResponse"
: array of objects, optional-
Defines a list of assignment bindings to evaluate after the response is handled.
"condition"
: runtime expression<boolean>, optional-
If the expression evaluates
true
, the value is assigned to the target.Default:
${true}
"target"
: <lvalue-expression>, required-
Expression that yields the target object whose value is to be set.
"value"
: runtime expression<object> , optional-
The value to be set in the target. The value can be a string, information from the context, or even a whole map of information.
Examples
The following example assigns a value to a session. Add the filter to a route to prevent IG from clearing up empty JWTSession cookies:
{
"type": "AssignmentFilter",
"config": {
"onRequest": [{
"target": "${session.authUsername}",
"value": "I am root"
}]
}
}
The following example captures credentials and stores them in the IG session during a login request. Notice that the credentials are captured on the request but are not marked as valid until the response returns a positive 302. The credentials could then be used to log a user in to a different application:
{
"name": "PortalLoginCaptureFilter",
"type": "AssignmentFilter",
"config": {
"onRequest": [
{
"target": "${session.authUsername}",
"value": "${request.queryParams['username'][0]}"
},
{
"target": "${session.authPassword}",
"value": "${request.queryParams['password'][0]}"
},
{
"comment": "Authentication has not yet been confirmed.",
"target": "${session.authConfirmed}",
"value": "${false}"
}
],
"onResponse": [
{
"condition": "${response.status.code == 302}",
"target": "${session.authConfirmed}",
"value": "${true}"
}
]
}
}
AuthorizationCodeOAuth2ClientFilter
The AuthorizationCodeOAuth2ClientFilter uses OAuth 2.0 delegated authorization to authenticate end users. The filter can act as an OpenID Connect relying party or as an OAuth 2.0 client.
AuthorizationCodeOAuth2ClientFilter performs the following tasks:
-
Allows the user to select an authorization server from one or more static client registrations, or by discovery and dynamic registration.
In static client registration, authorization servers are provided by Issuer, and registrations are provided by ClientRegistration.
-
Redirects the user through the authentication and authorization steps of an OAuth 2.0 authorization code grant, which results in the authorization server returning an access token to the filter.
-
When an authorization grant succeeds, injects the access token data into a configurable target in the context so that subsequent filters and handlers can access the access token. Subsequent requests can use the access token without authenticating again.
-
When an authorization grant fails, invokes a failureHandler.
Service URIs
Service URIs are constructed from the clientEndpoint
, as follows:
clientEndpoint/login/?discovery=user-input&goto=url
-
Discover and register dynamically with the end user’s OpenID Provider or with the client registration endpoint as described in RFC 7591, using the value of user-input.
After successful registration, redirect the end user to the provider for authentication and authorization consent. Then redirect the user agent back to the callback client endpoint, and then the goto URI.
The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.
To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.
clientEndpoint/login?registration=clientId&issuer=issuerName&goto=url
-
Redirect the end user for authorization with the specified registration, defined by the ClientRegistration’s
clientId
andissuerName
. For information, refer to ClientRegistration.The provider corresponding to the registration then authenticates the end user and obtains authorization consent before redirecting the user agent back to the callback client endpoint.
If successful, the filter saves the authorization state in the session and redirects the user agent to the goto URL.
The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.
To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.
clientEndpoint/logout?goto=url
-
Remove the authorization state for the end user, and redirect the request to the goto URL.
The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.
To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.
If no goto URL is specified in the request, use
defaultLogoutGoto
. clientEndpoint/callback
-
Handle the callback from the OAuth 2.0 authorization server, that occurs as part of the authorization process.
If the callback is handled successfully, the filter saves the authorization state in the context at the specified target location and redirects to the URL provided to the login endpoint during login.
- Other request URIs
-
Restore the authorization state in the specified target location, and call the next filter or handler in the chain.

"secretsProvider": SecretsProvider reference
}
}
Properties
"clientEndpoint"
: runtime expression<url>, required-
The URI to the client endpoint.
So that routes can accept redirects from the authorization server to the callback endpoint, the
clientEndpoint
must be the same as the route condition or a sub path of the route condition. For example:-
The same as the route condition:
"condition": "${find(request.uri.path, '^/discovery')}"
"clientEndpoint": "/discovery"
-
As a sub path of the route condition:
"condition": "${find(request.uri.path, '^/home/id_token')}"
"clientEndpoint": "/home/id_token/sub-path"
Service URIs are constructed from the
clientEndpoint
. For example, whenclientEndpoint
isopenid
, the service URIs are/openid/login
,/openid/logout
, and/openid/callback
. These endpoints are implicitly reserved, and attempts to access them directly can cause undefined errors.The result of the expression must be a string that represents a valid URI, but is not a real
java.net.URI
object. For example, it would be incorrect to use${request.uri}
, which is not a String but a MutableUri.See also Expressions.
-
"failureHandler"
: Handler reference, required-
An inline handler configuration object, or the name of a handler object that is defined in the heap.
When the OAuth 2.0 Resource Server denies access to a resource, the failure handler can be invoked only if the error response contains a WWW-Authenticate header (meaning that there was a problem with the OAuth 2.0 exchange). All other responses are forwarded to the user agent without invoking the failure handler.
If the value of the WWW-Authenticate header is
invalid_token
, the AuthorizationCodeOAuth2ClientFilter tries to refresh the access token:-
If the token is refreshed, the AuthorizationCodeOAuth2ClientFilter tries again to access the protected resource.
-
If the token is not refreshed, or if the second attempt to access the protected resource fails, the AuthorizationCodeOAuth2ClientFilter invokes the failure handler.
When the failure handler is invoked, the target in the context can be populated with information such as the exception, client registration, and error. The failure object in the target is a simple map, similar to the following example:
{ "client_registration": "ClientRegistration name string", "error": { "realm": "optional string", "scope": [ "string (required by the client)", ... ], "error": "optional string", "error_description": "optional string", "error_uri": "optional string" }, "access_token": "string", "id_token": "string", "token_type": "Bearer", "expires_in": "number", "scope": [ "optional scope string", ... ], "client_endpoint": "URL string", "exception": exception }
In the failure object, the following fields are not always present. Their presence depends on when the failure occurs:
-
"access_token"
-
"id_token"
-
"token_type"
-
"expires_in"
-
"scope"
-
"client_endpoint"
See also Handlers.
-
-
"loginHandler"
: Handler reference, required if there are zero or multiple client registrations, optional if there is one client registration-
Use this Handler when the user must choose an authorization server. When
registrations
contains only one client registration, this Handler is optional but is displayed if specified.Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object.
See also Handlers.
"registrations"
: array of ClientRegistration references optional-
List of client registrations that authenticate IG to the authorization server. The list must contain all client registrations that are to be used by the client filter.
The value represents a static client registration with an authorization server, as described in ClientRegistration.
"metadata"
: <object>, required for dynamic client registration and ignored otherwise-
The values of the object are evaluated as configuration expression<strings>.
This object holds client metadata as described in OpenID Connect Dynamic Client Registration 1.0, and optionally a list of scopes. See that document for additional details and a full list of fields.
This object can also hold client metadata as described in RFC 7591, OAuth 2.0 Dynamic Client Registration Protocol. See that RFC for additional details.
The following partial list of metadata fields is not exhaustive, but includes metadata that is useful with AM as OpenID Provider:
"redirect_uris"
: array of configuration expression<url>, required-
The array of redirection URIs to use when dynamically registering this client.
One of the registered values must match the
clientEndpoint
. "client_name"
: configuration expression<string>, optional-
Name of the client to present to the end user.
"scope"
: _configuration expression<string>, optional-
Space-separated string of scopes to request of the OpenID Provider, for example:
"scope": "openid profile"
This property is available for dynamic client registration with AM, or with authorization servers that support RFC 7591, OAuth 2.0 Dynamic Client Registration Protocol
"cacheExpiration"
: configuration expression<duration>, optional-
Duration for which to cache user-info resources.
IG lazily fetches user info from the OpenID provider. In other words, IG only fetches the information when a downstream Filter or Handler uses the user info. Caching allows IG to avoid repeated calls to OpenID providers when reusing the information over a short period.
Default: 10 minutes
Set this to disabled or zero to disable caching. When caching is disabled, user info is still lazily fetched.
"executor"
: ScheduledExecutorService reference, optional-
A ScheduledExecutorService to schedule the execution of tasks, such as the eviction of entries in the OpenID Connect user information cache.
Default:
ScheduledExecutorService
"target"
: lvalue-expression, optional-
An expression that yields the target object. Downstream filters and handlers can use data in the target to enrich the existing request or create a new request.
When the
target
isopenid
, the following information can be provided in${attributes.openid}
:-
access_token
: Value of the OAuth 2.0 access token -
scope
: Scopes associated with the OAuth 2.0 access token -
token_type
: Authentication token type; for example,Bearer
-
expires_in
: Number of milliseconds until the OAuth 2.0 access token expires -
id_token
: Value of the OpenID Connect token -
id_token_claims
: Claims used in the OpenID Connect token -
client_endpoint
: URL to the client endpoint -
client_registration
: Client ID of the OAuth 2.0 client that enables IG to communicate as an OAuth 2.0 client with an authorization server -
user_info
: Profile attributes of an authenticated user; for example,sub
,name
,family_name
Data is provided to the target as follows:
-
If the authorization process completes successfully, the AuthorizationCodeOAuth2ClientFilter injects the authorization state data into the target. In the following example, a downstream StaticRequestFilter retrieves the username and password from the target to log the user in to the sample application.
{ "type": "StaticRequestFilter", "config": { "method": "POST", "uri": "http://app.example.com:8081/login", "form": { "username": [ "${attributes.openid.user_info.sub}" ], "password": [ "${attributes.openid.user_info.family_name}" ] } } }
For information about setting up this example, refer to Authenticate Automatically to the Sample Application.
-
If the failure handler is invoked, the target can be populated with information such as the exception, client registration, and error, as described in "failureHandler" in this reference page.
Default:
${attributes.openid}
See also Expressions.
-
"defaultLoginGoto"
: runtime expression<url>,optional-
After successful authentication and authorization, if the user accesses the
clientEndpoint/login
endpoint without providing a landing page URL in thegoto
parameter, the request is redirected to this URI.The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.
To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.
The result of the expression must be a string that represents a valid URI, but is not a real
java.net.URI
object. For example, it would be incorrect to use${request.uri}
, which is not a String but a MutableUri.Default: return an empty page.
"defaultLogoutGoto"
: runtime expression<url>,optional-
If the user accesses the
clientEndpoint/logout
endpoint without providing a goto URL, the request is redirected to this URI.The goto URL must use the same scheme, host, and port as the original URI, or be a relative URI (just the path). Otherwise, the request fails with an error.
To redirect a request to a site that does not meet the goto URL criteria, change the original URI by using a ForwardedRequestFilter.
The result of the expression must be a string that represents a valid URI, but is not a real
java.net.URI
object. For example, it would be incorrect to use${request.uri}
, which is not a String but a MutableUri.Default: return an empty page.
"requireHttps"
: configuration expression<boolean>, optional-
Whether to require that original target URI of the request (
originalUri
in UriRouterContext) uses the HTTPS scheme.If the received request does not use HTTPS, it is rejected.
Default: true.
"requireLogin"
: configuration expression<boolean>, optional-
Whether to require authentication for all incoming requests.
Default: true.
"issuerRepository"
: Issuer repository reference, optional-
A repository of OAuth 2.0 issuers, built from discovered issuers and the IG configuration.
Provide the name of an IssuerRepository object defined in the heap.
Default: Look up an issuer repository named
IssuerRepository
in the heap. If none is explicitly defined, then a default one namedIssuerRepository
is created in the current route.See also IssuerRepository.
"discoveryHandler"
: Handler reference, optional-
Use this property for discovery and dynamic registration of OpenID Connect clients.
Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object. Usually set this to the name of a ClientHandler configured in the heap, or a chain that ends in a ClientHandler.
Default: The default ClientHandler.
See also Handlers, ClientHandler.
"discoverySecretId"
: configuration expression<secret-id>, required for discovery and dynamic registration-
Use this property for discovery and dynamic registration of OAuth 2.0 clients.
This secret ID must point to a
CryptoKey
.Specifies the secret ID of the secret that is used to sign a JWT before the JWT is sent to the authorization server.
If
discoverySecretId
is used, then thetokenEndpointAuthMethod
is alwaysprivate_key_jwt
. "tokenEndpointAuthMethod"
: configuration expression<enumeration>, optional-
Use this property for discovery and dynamic registration of OAuth 2.0 clients.
The authentication method with which a client authenticates to the authorization server or OpenID provider at the token endpoint. For information about client authentication methods, refer to OpenID Client Authentication. The following client authentication methods are allowed:
-
client_secret_basic
: Clients that have received aclient_secret
value from the authorization server authenticate with the authorization server by using HTTP basic access authentication, as in the following example:POST /oauth2/token HTTP/1.1 Host: as.example.com Authorization: Basic .... Content-Type: application/x-www-form-urlencoded grant_type=authorization_code& code=...
-
client_secret_post
: Clients that have received aclient_secret
value from the authorization server authenticate with the authorization server by including the client credentials in the request body, as in the following example:POST /oauth2/token HTTP/1.1 Host: as.example.com Content-Type: application/x-www-form-urlencoded grant_type=authorization_code&; client_id=...& client_secret=...& code=...
-
private_key_jwt
: Clients send a signed JSON Web Token (JWT) to the authorization server. IG builds and signs the JWT, and prepares the request as in the following example:POST /token HTTP/1.1 Host: as.example.com Content-Type: application/x-www-form-urlencoded grant_type=authorization_code& code=...& client_id=<clientregistration_id>& client_assertion_type=urn%3Aietf%3Aparams%3Aoauth%3Aclient-assertion-type%3Ajwt-bearer& client_assertion=PHNhbWxwOl ... ZT
If the authorization server doesn’t support
private_key_jwt
, a dynamic registration falls back on the method returned by the authorization server, for example,client_secret_basic
orclient_secret_post
.If
tokenEndpointAuthSigningAlg
is not configured, theRS256
signing algorithm is used forprivate_key_jwt
.Consider these points for identity providers:
-
Some providers accept more than one authentication method.
-
If a provider strictly enforces how the client must authenticate, align the authentication method with the provider.
-
If a provider doesn’t support the authentication method, the provider sends an HTTP 400 Bad Request response with an
invalid_client
error message, according to RFC 6749: Error Response. -
If the authentication method is invalid, the provider sends an
IllegalArgumentException
.
-
Default: If
discoverySecretId
is used, then thetokenEndpointAuthMethod
is alwaysprivate_key_jwt
. Otherwise, it isclient_secret_basic
. -
"tokenEndpointAuthSigningAlg"
: configuration expression<string>, optional-
The JSON Web Algorithm (JWA) used to sign the JWT that is used to authenticate the client at the token endpoint. The property is used when
private_key_jwt
is used for authentication.If the authorization server sends a notification to use a different algorithm to sign the JWT, that algorithm is used.
Default: If
discoverySecretId
is used, then thetokenEndpointAuthSigningAlg
isRS256
. Otherwise, it is not used.
"oAuth2SessionKey"
: configuration expression<string>, optional-
A key to identify an OAuth 2.0 session. The key can be any character string.
To share the same OAuth 2.O session when a user accesses different applications protected by IG, use the same key in each filter.
Default: The complete client endpoint URI. AuthorizationCodeOAuth2ClientFilters do not share OAuth 2.O sessions.
"secretsProvider"
: SecretsProvider reference, required ifdiscoverySecretId
is used-
The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.
More information
OpenID Connect site, in particular the list of standard OpenID Connect 1.0 scope values.
CapturedUserPasswordFilter
Makes an AM password available to IG in the following steps:
-
Checks for the presence of the SessionInfoContext context, at
${contexts.amSession}
.-
If the context is not present, or if
sunIdentityUserPassword
isnull
, the CapturedUserPasswordFilter collects session info and properties from AM. -
If the context is present and
sunIdentityUserPassword
is notnull
, the CapturedUserPasswordFilter uses that value for the password.
-
-
The CapturedUserPasswordFilter decrypts the password and stores it in the CapturedUserPasswordContext, at
${contexts.capturedPassword}
.

CertificateThumbprintFilter
Extracts a Java certificate from a trusted header or from a TLS connection, computes the SHA-256 thumbprint of that certificate, and makes the thumbprint available for the ConfirmationKeyVerifierAccessTokenResolver. Use this filter to enable verification of certificate-bound access tokens.
CertificateThumbprintFilter computes and makes available the SHA-256 thumbprint of a client certificate as follows:
-
Evaluates a runtime expression and yields a
java.security.cert.Certificate
-
Hashes the certificate using SHA-256
-
Base64url-encodes the result
-
Stores the result in the contexts chain
The runtime expression can access or build a client certificate from any information present at runtime, such as a PEM in a header, or a pre-built certificate.
Use CertificateThumbprintFilter with ConfirmationKeyVerifierAccessTokenResolver when the IG instance is behind the TLS termination point, for example, when IG is running behind a load balancer or other ingress point.
Usage
{
"name": string,
"type": "CertificateThumbprintFilter",
"config": {
"certificate": runtime expression<certificate>,
"failureHandler": Handler reference,
}
}
Properties
"certificate"
: runtime expression<certificate>, required-
An EL expression which, when evaluated, yields an instance of a
java.security.cert.Certificate
.Use the following Functions in the expression to define hash, decoding, and certificate format:
-
digestSha256
, to calculate the SHA-256 hash of the certificate. -
decodeBase64url
, to decode an incoming base64url-encoded string. -
pemCertificate
, to convert a PEM representation string into a certificate.
See Examples.
-
Examples
The following example use the certificate associated with the incoming HTTP connection:
{
"name": "CertificateThumbprintFilter-1",
"type": "CertificateThumbprintFilter",
"config": {
"certificate": "${contexts.client.certificates[0]}"
}
}
The following example is adapted for a deployment with NGINX as the TLS
termination, where NGINX fronts IG. NGINX provides the client
certificate associated with its own incoming connection in the
x-ssl-client-cert
header. The certificate is encoded as PEM, and then
url-encoded:
{
"name": "CertificateThumbprintFilter-2",
"type": "CertificateThumbprintFilter",
"config": {
"certificate": "${pemCertificate(urlDecode(request.headers['x-ssl-client-cert'][0]))}"
}
}
CircuitBreakerFilter
Monitors failures. When the number of failures reaches a configured failure threshold, the circuit breaker trips, and the circuit is considered open. Calls to downstream filters are stopped, and a runtime exception is returned.
After a configured delay, the circuit breaker is reset, and is the circuit considered closed. Calls to downstream filters are restored.
Usage
{
"name": string,
"type": "CircuitBreakerFilter",
"config": {
"maxFailures": configuration expression<integer>,

"size"
: configuration expression<number>, required-
The size of the sliding window in which to count errors.
The value of
size
must be greater than zero, and greater than the value ofmaxFailures
, otherwise an exception is thrown.

openDuration
.Default: The default ScheduledExecutorService in the heap
Example
In the following example, the circuit breaker opens after 11 failures in the previous 100 requests, throwing a runtime exception with a "circuit-breaker open" message. The default ScheduledExecutorService in the heap closes the circuit-breaker after 10 seconds.
{
"type": "CircuitBreakerFilter",
"config": {
"maxFailures": 10,
"openDuration": "10 seconds",
"openHandler": {
"type": "StaticResponseHandler",
"config": {

}
}
}
ClientCredentialsOAuth2ClientFilter
Authenticates OAuth 2.0 clients by using the client’s OAuth 2.0 credentials to obtain an access token from an authorization server, and injecting the access token into the inbound request as a Bearer Authorization header. The access token is valid for the configured scopes.
The ClientCredentialsOAuth2ClientFilter obtains the client’s access token by
using the client_credentials
grant type. Client authentication is provided by
the endpointHandler
property, which uses a client authentication filter, such
as
ClientSecretBasicAuthenticationFilter.
The filter refreshes the access token as required.
Use the ClientCredentialsOAuth2ClientFilter in a service-to-service context, where services need to access resources protected by OAuth 2.0.
Usage

The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.
Example
{
"name": "ExchangeHandler",
"type": "Chain",
"config": {
"handler": "ForgeRockClientHandler",
"filters": [
{
"type": "ClientSecretBasicAuthenticationFilter",
"config": {

Host: as.example.com
Content-Type: application/x-www-form-urlencoded
grant_type=authorization_code&;
client_id=...&
client_secret=...&
code=...
Use this filter with an endpoint Handler
that requires client_secret_post
authentication. For example, endpointHandler
in the
OAuth2TokenExchangeFilter or
ClientCredentialsOAuth2ClientFilter.
Usage
{
"name": string,
"type": "ClientSecretPostAuthenticationFilter",
"config": {
"clientId": configuration expression<string>,
"clientSecretId": configuration expression<secret-id>,

ConditionalFilter
Verifies that a specified condition is met. If the condition is met, the request is dispatched to a delegate Filter. Otherwise, the delegate Filter is skipped.
Use ConditionalFilter
to easily use or skip a Filter depending on whether a
condition is met. To easily use or skip a set of Filters, use a ChainOfFilters
as the delegate Filter and define a set of Filters. For information, refer to
ChainOfFilters.
Usage
{
"name": string,
"type": "ConditionalFilter",
"config": {
"condition": runtime expression<boolean>,
"delegate": Filter reference
}
}
Properties
"condition"
: runtime expression<boolean>, required-
If the expression evaluates to
true
, the request is dispatched to the delegate Filter. Otherwise the delegate Filter is skipped. "delegate"
: Filter reference, required-
Filter to treat the request when the condition expression evaluates as
true
.See also Filters.
Example
The following example tests whether a request finishes with .js
or .jpg
:
{
"type": "Chain",
"config": {
"filters": [{
"type": "ConditionalFilter",
"config": {
"condition": "${not (find(request.uri.path, '.js$') or find(request.uri.path, '.jpg$'))}",
"delegate": "mySingleSignOnFilter"
}
}],
"handler": "ReverseProxyHandler"
}
}
If the request is to access a .js file or .jpg file, it skips the delegate SingleSignOnFilter filter declared in the heap, and passes straight to the ReverseProxyHandler.
If the request is to access another type of resource, it must pass through the delegate SingleSignOnFilter for authentication with AM before it can pass to the ReverseProxyHandler.
ConditionEnforcementFilter
Verifies that a specified condition is met. If the condition is met, the request continues to be executed. Otherwise, the request is referred to a failure handler, or IG returns 403 Forbidden and the request is stopped.
Usage
{
"name": string,
"type": "ConditionEnforcementFilter",
"config": {
"condition": runtime expression<boolean>,
"failureHandler": Handler reference
}
}
Properties
"condition"
: runtime expression<boolean>, required-
If the expression evaluates to
true
, the request continues to be executed. "failureHandler"
: Handler reference, optional-
Handler to treat the request if the condition expression evaluates as
false
.Provide an inline handler configuration object, or the name of a handler object declared in the heap. See also Handlers.
Default: HTTP 403 Forbidden, the request stops being executed.
Example
The following example tests whether a request contains a session username. If it
does, the request continues to be executed. Otherwise, the request is dispatched
to the ConditionFailedHandler
failure handler.
{
"name": "UsernameEnforcementFilter",
"type": "ConditionEnforcementFilter",
"config": {
"condition": "${not empty (session.username)}",
"failureHandler": "ConditionFailedHandler"
}
}
ChainOfFilters
Dispatches a request to an ordered list of filters. Use this filter to assemble a list of filters into a single filter that you can then use in different places in the configuration.
A ChainOfFilters can be placed in a configuration anywhere that a filter can be placed.
Unlike Chain
, ChainOfFilters
does not finish by dispatching the request to
a handler. For more information, refer to Chain.
Usage
{
"name": string,
"type": "ChainOfFilters",
"config": {
"filters": [ Filter reference, ... ]
}
}
Properties
"filters"
: array of Filter references, required-
An array of names of filter objects defined in the heap, and inline filter configuration objects.
The chain dispatches the request to these filters in the order they appear in the array.
See also Filters.
Example
{
"name": "MyChainOfFilters",
"type": "ChainOfFilters",
"config": {
"filters": [ "Filter1", "Filter2" ]
}
}
CookieFilter
Manages, suppresses, and relays cookies for stateful sessions. This filter is not currently compatible with stateless sessions.
Usage
{
"name": string,
"type": "CookieFilter",
"config": {
"managed": [ configuration expression<string>, ... ],
"suppressed": [ configuration expression<string>, ... ],
"relayed": [ configuration expression<string>, ... ],
"defaultAction": configuration expression<enumeration>
}
}
Properties
"managed"
: array of configuration expression<strings>, optional-
A list of the names of cookies to be managed.
IG stores cookies from the protected application in the session and manages them as follows:
-
Requests with a
Cookie
header: IG removes managed cookies so that protected applications cannot see them. -
Responses with a
Set-Cookie
header: IG removes managed cookies and keeps a copy of them. IG then adds the managed cookies in aCookie
header to future requests that traverse the CookieFilter.
-
"suppressed"
: array of configuration expression<strings>, optional-
A list of the names of cookies to be suppressed.
IG removes cookies from the request and response. Use this option to hide domain cookies, such as the AM session cookie, that are used by IG but are not usually used by protected applications.
"relayed"
: array of configuration expression<strings>, optional-
A list of the names of cookies to be relayed.
IG transmits cookies freely from the user agent to the remote server, and vice versa.
"defaultAction"
: configuration expression<enumeration>, optional-
Action to perform for cookies that do not appear in one of the above lists. Set to
MANAGE
,SUPPRESS
, orRELAY
.If a cookie appears in more than one of the above lists, it is treated in the following order of precedence:
managed
,suppressed
,relayed
. For example, if a cookie is in both themanaged
andrelayed
lists, the cookie is managed.Default:
"MANAGE"
.
CorsFilter
Configures policies for cross-origin resource sharing (CORS), to allow cross-domain requests from user agents.
Usage

"config": {
"policies": [ object, ... ],
"failureHandler": Handler reference
}
}
Properties
"policies"
: array of objects, required-
One or more policies to apply to the request. A policy is selected when the origin of the request matches the accepted
origins
of the policy.When multiple policies are declared, they are tried in the order that they are declared, and the first matching policy is selected.
{ "acceptedOrigins": [ configuration expression<url>, ... ] or "*", "acceptedMethods": [ configuration expression<string>, ... ] or "*", "acceptedHeaders": [ configuration expression<string>, ... ] or "*", "exposedHeaders": [ configuration expression<string>, ... ], "maxAge": configuration expression<duration>, "allowCredentials": configuration expression<boolean>, "origins": [ configuration expression<url>, ... ] or "*" //deprecated }
"acceptedOrigins"
: array of configuration expression<urls> or"*"
, required-
A comma-separated list of origins, to match the origin of the CORS request. Alternatively, use
*
to allow requests from any URL.If the request origin is not in the list of accepted origins, the failure handler is invoked or an HTTP 403 Forbidden is returned, and the request stops being executed.
Origins are URLs with a scheme, hostname, and optionally a port number, for example,
http://www.example.com
. If a port number is not defined, origins with no port number or with the default port number (80 for HTTP, 443 for HTTPS) are accepted.Examples:
{ "acceptedOrigins": [ "http://www.example.com", "https://example.org:8433" ] }
{ "acceptedOrigins": "*" }
"acceptedMethods"
: array of configuration expression<strings> or"*"
, optional-
A comma-separated list of case-sensitive HTTP method names that are allowed when making CORS requests. Alternatively, use
*
to allow requests with any method.In preflight requests, browsers use the
Access-Control-Request-Method
header to let the server know which HTTP method might be used in the actual request.-
If all requested methods are allowed, the requested methods are returned in the preflight response, in the
Access-Control-Allow-Methods
header. -
If any requested method is not allowed, the
Access-Control-Allow-Methods
header is omitted. The failure handler is not invoked, but the user agent interprets the preflight response as a CORS failure.
Examples:
{ "acceptedMethods": [ "GET", "POST", "PUT", "MyCustomMethod" ] }
{ "acceptedMethods": "*" }
Default: All methods are rejected.
-
"acceptedHeaders"
: array of configuration expression<strings> or"*"
, optional-
A comma-separated list of case-insensitive request header names that are allowed when making CORS requests. Alternatively, use
*
to allow requests with any header.In preflight requests, browsers use the
Access-Control-Request-Headers
header to let the server know which HTTP headers might be used in the actual request.-
If all requested headers are allowed, the requested headers are returned in the preflight response, in the
Access-Control-Allow-Headers
header. -
If any requested header is not allowed, the
Access-Control-Allow-Headers
header is omitted. The failure handler is not invoked, but the user agent interprets the preflight response as a CORS failure.
Examples:
{ "acceptedHeaders": [ "iPlanetDirectoryPro", "X-OpenAM-Username", "X-OpenAM-Password", "Accept-API-Version", "Content-Type", "If-Match", "If-None-Match" ] }
{ "acceptedHeaders": "*" }
Default: All requested headers are rejected.
-
"exposedHeaders"
: list of configuration expression<string>, optional-
A comma-separated list of case-insensitive response header names that are returned in the
Access-Control-Expose-Headers
header.Only headers in this list, safe headers, and the following simple response headers are exposed to frontend JavaScript code:
-
Cache-Control
-
Content-Language
-
Expires
-
Last-Modified
-
Pragma
-
Content-Type
Example:
{ "exposedHeaders": [ "Access-Control-Allow-Origin", "Access-Control-Allow-Credentials", "Set-Cookie" ] }
-
Default: No headers are exposed.
"maxAge"
: configuration expression<duration>, optional-
The maximum duration for which a browser is allowed to cache a preflight response. The value is included in the
Access-Control-Max-Age
header of preflight responses.When this
maxAge
is greater than the browser’s maximum internal value, the browser value takes precedence.Default: 5 seconds
"allowCredentials"
: configuration expression<boolean>, optional-
A flag to allow requests that use credentials, such as cookies, authorization headers, or TLS client certificates.
Set to
true
to set theAccess-Control-Allow-Credentials
header totrue
, and allow browsers to expose the response to frontend JavaScript code.Default: False
"origins"
: list of configuration expression<url> or "*", required-
This property is deprecated; use acceptedOrigins
instead. For more information, refer to the Deprecated section of the Release Notes.A comma-separated list of origins, to match the origin of the CORS request. Alternatively, use
*
to allow requests from any URL.Origins are URLs with a scheme, hostname, and optionally a port number, for example,
http://www.example.com
. If a port number is not defined, origins with no port number or with the default port number (80 for HTTP, 443 for HTTPS) are accepted.
"failureHandler"
: Handler reference, optional-
Handler invoked during the preflight request, when the request origin does not match any of the
acceptedOrigins
defined inpolicies
.The failure handler is not invoked when requested headers or requested methods are not allowed.
Provide an inline handler configuration object, or the name of a handler object declared in the heap. See also Handlers.
Default: HTTP 403 Forbidden, the request stops being executed.
CrossDomainSingleSignOnFilter
When IG and AM are running in the same domain, the SingleSignOnFilter can be used for SSO. When IG and AM are running in different domains, AM cookies are not visible to IG because of the same-origin policy. The CrossDomainSingleSignOnFilter provides a mechanism to push tokens issued by AM to IG running in a different domain.
When this filter processes a request, it injects the CDSSO token, the session user ID, and the full claims set into the CdSsoContext. Should an error occur during authentication, the error details are captured in a CdSsoFailureContext.
For an example of how to configure CDSSO in AM and IG, and information about the flow of data between AM, IG, and a protected application, refer to Authenticate with CDSSO.
WebSocket notifications for sessions
When WebSocket notifications are set up for sessions, IG receives a
notification from AM when a user logs out of AM, or when the
AM session is modified, closed, or times out. IG then evicts
entries that are related to the event from the sessionCache
.
For information about setting up WebSocket notifications, using them to clear the session cache, and including them in the server logs, refer to WebSocket notifications.
Usage
{
"name": string,
"type": "CrossDomainSingleSignOnFilter",
"config": {
"amService": AmService reference,
"redirectEndpoint": configuration expression<url>,
"authenticationService": configuration expression<string>,
"authCookie": object,
"redirectionMarker": object,
"defaultLogoutLandingPage": configuration expression<url>,
"logoutExpression": runtime expression<boolean>,
"failureHandler": Handler reference,
"verificationSecretId": configuration expression<secret-id>,
"secretsProvider": SecretsProvider reference
}
}
Properties
"amService"
: AmService reference, required-
The AmService heap object to use. See AmService.
"redirectEndpoint"
: configuration expression<url>, required-
The URI to which AM redirects the browser with the authentication token or an authentication error. The filter checks that the authentication was initiated by IG.
Configure this URI to be the same as that in AM.
To make sure the redirect is routed back to the CrossDomainSingleSignOnFilter, include the endpoint in the route condition in one of the following ways:
-
As a sub-path of the condition path.
For example, use the following route condition with the following endpoint:
"condition": "${find(request.uri.path, '^/home/cdsso')}"
"redirectEndpoint": "/home/cdsso/callback"
-
To match the route condition.
For example, use the following route condition with the following endpoint:
"condition": "${find(request.uri.path, '^/home/cdsso')}"
"redirectEndpoint": "/home/cdsso"
With this route condition, all POST requests on the condition path are treated as AM CDSSO callbacks. Any POST requests that aren’t the result of an AM CDSSO callback will fail.
-
As a specific path that is not related to the condition path.
To make sure the redirect is routed back to this filter, include the redirectEndpoint as a path in the filter condition.
For example, use the following route condition with the following endpoint:
"condition": "${find(request.uri.path, '^/home/cdsso/redirect') || find(request.uri.path, '^/ig/cdssoRedirectUri')}"
"redirectEndpoint": "/ig/cdssoRedirectUri"
-
"authenticationService"
: configuration expression<string>,optional-
The name of an AM authentication tree or authentication chain to use for authentication.
Use only authentication trees with ForgeRock Identity Cloud. Authentication modules and chains are not supported. Default: AM’s default authentication tree.
For more information about authentication trees and chains, refer to Authentication nodes and trees and Authentication modules and chains in AM’s Authentication and SSO guide.
"authCookie"
: object, optional-
The configuration of the cookie used to store the authentication.
{ "name": configuration expression<string>, "domain": configuration expression<string>, "httpOnly": configuration expression<boolean>, "path": configuration expression<string>, "sameSite": configuration expression<enumeration>, "secure": configuration expression<boolean> }
"name"
: configuration expression<string>, optional-
Name of the cookie containing the authentication token from AM.
For security, change the default name of cookies.
Default:
ig-token-cookie
"domain"
: configuration expression<string>, optional-
Domain to which the cookie applies.
Set a domain only if the user agent is able to re-emit cookies on that domain on its next hop. For example, to re-emit a cookie on the domain
example.com
, the user agent must be able to access that domain on its next hop.Default: The fully qualified hostname of the user agent’s next hop.
"httpOnly"
: configuration expression<boolean>, optional-
Flag to mitigate the risk of client-side scripts accessing protected cookies.
Default:
true
"path"
: configuration expression<string>, optional-
Path protected by this authentication.
Set a path only if the user agent is able to re-emit cookies on the path. For example, to re-emit a cookie on the path
/home/cdsso
, the user agent must be able to access that path on its next hop.Default: The path of the request that got the
Set-Cookie
in its response. "sameSite"
: configuration expression<enumeration>, optional-
Options to manage the circumstances in which a cookie is sent to the server. Use one of the following values to reduce the risk of CSRF attacks:
-
STRICT
: Send the cookie only if the request was initiated from the cookie domain. Not case-sensitive.Use this value to reduce the risk of cross-site request forgery (CSRF) attacks.
-
LAX
: Send the cookie only with GET requests in a first-party context, where the URL in the address bar matches the cookie domain. Not case-sensitive.Use this value to reduce the risk of cross-site request forgery (CSRF) attacks.
-
NONE
: Send the cookie whenever a request is made to the cookie domain. Not case-sensitive.With this setting, consider setting
secure
totrue
to prevent browsers from rejecting the cookie. For more information, refer to SameSite cookies.
Default:
LAX
-
For CDSSO, set "sameSite":"none"
and"secure":"true"
. For security reasons, many browsers require the connection used by the browser to be secure (HTTPS) for"sameSite":"none"
. Therefore, if the connection used by the browser is not secure (HTTP), the browser might not supply cookies with"sameSite":"none"
. For more information, refer to Authenticate with CDSSO."secure"
: configuration expression<boolean>, optional-
Flag to limit the scope of the cookie to secure channels.
Set this flag only if the user agent is able to re-emit cookies over HTTPS on its next hop. For example, to re-emit a cookie with the
secure
flag, the user agent must be connected to its next hop by HTTPS.Default:
false
"redirectionMarker"
: configuration expression<object>, optional-
A redirect marker for the CDSSO flow. If the marker is present in the CDSSO flow, the request is not redirected for authentication.
This feature is on by default to prevent redirect loops when the session cookie is not present in the CDSSO flow. The cookie can be absent from the flow if it is bigger than 4 KB, or if the cookie domain does not include IG’s domain.
"redirectionMarker": { "enabled": configuration expression<boolean>, "name": configuration expression<string> }
"enabled"
: configuration expression<boolean>, optional-
When true, the named redirection marker is used to protect against infinite authentication loops.
Default:
true
"name"
: configuration expression<string>, optional-
The name of the redirectionMarker query parameter to use when
redirectionMarker
is enabled.Default:
_ig
"defaultLogoutLandingPage"
: configuration expression<url>, optional-
The URL to which a request is redirected if
logoutExpression
is evaluated as true.If this property is not an absolute URL, the request is redirected to the IG domain name.
This parameter is effective only when
logoutExpression
is specified.Default: None, processing continues.
"logoutExpression"
: runtime expression<boolean>, optional-
A flag to indicate whether a request initiates logout processing before reaching the protected application.
-
false
: The request does not initiate logout processing:-
If a valid AM session is found, the request is forwarded to the protected application.
-
If a valid AM session is not found, the request triggers login.
-
-
true
: The request initiates logout processing:-
If a valid AM session is found, the session is revoked and the request is forwarded as follows:
-
If
defaultLogoutLandingPage
is defined, the request is forwarded to the specified logout page. -
If
defaultLogoutLandingPage
is not defined, the request is forwarded to the protected application without any other validation.
-
-
If a valid session is not found, the request is forwarded to the protected application without any other validation.
-
To prevent unwanted access to the protected application, use
logoutExpression
with extreme caution as follows:-
Define a
defaultLogoutLandingPage
. -
If you don’t define a
defaultLogoutLandingPage
, specifylogoutExpression
to resolve totrue
only for requests that target dedicated logout pages of the protected application.
Consider the following examples when a
defaultLogoutLandingPage
is not configured:-
This expression resolves to
true
only for requests with/app/logout
in their path:"logoutExpression": ${startsWith(request.uri.rawPath, '/app/logout')}
When a request matches the expression, the AM session is revoked and the request is forwarded to the
/app/logout
page. -
This expression resolves to
true
for all requests that containlogOff=true
in their query parameters:"logoutExpression": ${find(request.uri.query, 'logOff=true')}
When a request matches the expression, the AM session is revoked and the request is forwarded to the protected application without any other validation. In this example, an attacker can bypass IG’s security mechanisms by simply adding
?logOff=true
to a request.
Default:
${false}
-
"failureHandler"
: Handler reference, optional-
Handler to treat the request if an error occurs during authentication.
If an error occurs during authentication, a CdSsoFailureContext is populated with details of the error and any associated
Throwable
. This is available to the failure handler so that it can respond appropriately.Be aware that the failure handler does not itself play a role in user authentication. It is only invoked if there is a problem that prevents user authentication from taking place.
A number of circumstances may cause the failure handler to be invoked, including:
-
The redirect endpoint is invalid.
-
The redirect endpoint is invoked without a valid CDSSO token.
-
The redirect endpoint is invoked inappropriately.
-
An error was reported by AM during authentication.
If no failure handler is configured, the default failure handler is used.
See also Handlers.
Default: HTTP 200 OK. The response entity contains details of the error.
-
"verificationSecretId"
: configuration expression<secret-id>, optional-
For the security of your deployment, always configure verificationSecretId
in CrossDomainSingleSignOnFilter.
WhenverificationSecretId
is not configured, IG does not verify the signature of AM session tokens, increasing the risk of CDSSO token tampering.The secret ID for the secret to verify the signature of AM session tokens.
verificationSecretId
must point to a CryptoKey.For information about how IG verifies signatures, refer to Validating the signature of signed tokens. For information about how secret stores resolve named secrets, refer to Secrets.
"secretsProvider"
: SecretsProvider reference, required-
The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.
Example
For an example that uses the CrossDomainSingleSignOnFilter, refer to Cross-domain single sign-on (CDSSO).

CsrfFilter
Prevent Cross Site Request Forgery (CSRF) attacks when using cookie-based authentication, as follows:
-
When a session is created or updated for a client, generate a CSRF token as a hash of the session cookie.
-
Send the token in a response header to the client, and require the client to provide that header in subsequent requests.
-
In subsequent requests, compare the provided token to the generated token.
-
If the token is not provided or can’t be validated, reject the request and return a valid CSRF token transparently in the response header.
Rogue websites that attempt CSRF attacks operate in a different website domain to the targeted website. Because of same-origin policy, rogue websites can’t access a response from the targeted website, and cannot, therefore, access the CSRF token.
Usage

DataPreservationFilter
The DataPreservationFilter triggers POST data preservation when an unauthenticated client posts HTML form data to a protected resource.
When an authentication redirect is triggered, the filter stores the data in the HTTP session, and redirects the client for authentication. After authentication, the filter generates an empty self-submitting form POST to emulate the original POST. It then replays the stored data into the request before passing it along the chain.
The data can be any POST content, such as HTML form data or a file upload.
For more information, refer to POST data preservation.
Usage
{
"type": "DataPreservationFilter",
"config": {
"noJavaScriptMessage": configuration expression<string>,
"maxContentLength": configuration expression<positive integer>
}
}
Properties
"noJavaScriptMessage"
: configuration expression<string>, optional-
JavaScript is used to replay the preserved data from the original POST that triggered the login redirect. This property configures a message to display if the user-agent does not support JavaScript.
Default:
Javascript is disabled in your browser, click on this button to replay the preserved original request
"maxContentLength"
: configuration expression<positive integer>, optional-
The maximum number of bytes of POST data the filter can preserve. The size is taken from the Content-Length header.
Default: 4096
Example

"handler": {
"type": "Chain",
"config": {
"filters": [{
...
},
{
"type": "DateHeaderFilter"
}

EncryptedPrivateKeyJwtClientAuthenticationFilter
Supports client authentication with the private_key_jwt
client-assertion,
using a signed and encrypted JWT.
Clients send a signed and encrypted JWT to the authorization server. IG builds, signs and encrypts the JWT, and prepares the request as in the following example:
POST /token HTTP/1.1
Host: as.example.com
Content-Type: application/x-www-form-urlencoded
grant_type=authorization_code&
code=...&
client_id=<clientregistration_id>&
client_assertion_type=urn%3Aietf%3Aparams%3Aoauth%3Aclient-assertion-type%3Ajwt-bearer&
client_assertion=PHNhbWxwOl ... ZT
Use this filter with an endpoint Handler
that requires authentication with the
private_key_jwt
client-assertion, using an encrypted JWT. For example, the
endpointHandler
handler in the
OAuth2TokenExchangeFilter.

EntityExtractFilter
Extracts regular expression patterns from a message entity, and stores their
values in a target
object. Use this object in password replay, to find a login
path or extract a nonce.
If the message type
is REQUEST
, the pattern is extracted before the request
is handled. If the message type
is RESPONSE
, the pattern is extracted out of
the response body.
Each pattern can have an associated template, which is applied to its match result.
For information, see Patterns.
Usage
{
"name": string,
"type": "EntityExtractFilter",
"config": {
"messageType": configuration expression<enumeration>,
"charset": configuration expression<string>,

Examples
Extracts a nonce from the response, which is typically a login page, and sets
its value in the attributes context to be used by the downstream filter posting
the login form. The nonce value would be accessed using the following
expression: ${attributes.extract.wpLoginToken}
.
The pattern finds all matches in the HTTP body of the form
wpLogintokenvalue="abc"
. Setting the template to $1
assigns the value
abc
to attributes.extract.wpLoginToken
:
{
"name": "WikiNoncePageExtract",
"type": "EntityExtractFilter",
"config": {
"messageType": "response",
"target": "${attributes.extract}",
"bindings": [
{
"key": "wpLoginToken",
"pattern": "wpLoginToken\"\\s.*value=\"(.*)\"",
"template": "$1"
}
]
}
}
The following example reads the response looking for the AM login page.
When found, it sets isLoginPage = true
to be used in a SwitchFilter to post
the login credentials:
{
"name": "FindLoginPage",
"type": "EntityExtractFilter",
"config": {
"messageType": "response",
"target": "${attributes.extract}",
"bindings": [

]
}
}
FapiInteractionIdFilter
Tracks the interaction ID of requests, according to the Financial-grade API (FAPI) WG, as follows:
-
If a FAPI header is provided in a client request, includes the interaction ID in the
x-fapi-interaction-id
property of the response header. -
If a FAPI header is not provided in the request, includes a new Universally Unique Identifier (UUID) in the
x-fapi-interaction-id
property of the response header. -
Adds the value of
x-fapi-interaction-id
to the log.
Example
The following example, based on Validate Certificate-Bound Access Tokens, adds a FapiInteractionIdFilter to the end of the chain:
{
"name": "mtls",
"condition": "${find(request.uri.path, '/mtls')}",
"handler": {
"type": "Chain",
"config": {
"filters": [ {
"name": "OAuth2ResourceServerFilter-1",
...
},
{
"type": "FapiInteractionIdFilter"
}
],
"handler": {
"name": "StaticResponseHandler-1",
...
}
}
}
}
FragmentFilter
Tracks the fragment part of a URI when a request triggers a login redirect.
-
Before authentication, the filter captures the URI fragment information and stores it in a cookie.
-
After authentication, when the request is issued again to the original URI, the filter redirects the browser to the original URI, including any URI fragment.
Use this filter with SingleSignOnFilter, CrossDomainSingleSignOnFilter, AuthorizationCodeOAuth2ClientFilter, and PolicyEnforcementFilter. This filter is not required for SAML because the final redirect is done with a DispatchHandler and a StaticResponseFilter.

-
NONE
: Send the cookie whenever a request is made to the cookie domain. Not case-sensitive.With this setting, consider setting
secure
totrue
to prevent browsers from rejecting the cookie. For more information, refer to SameSite cookies.

"secure"
: configuration expression<boolean>, optional-
Flag to limit the scope of the cookie to secure channels.
Default:
false
"maxAge"

FileAttributesFilter
Retrieves and exposes a record from a delimiter-separated file. Lookup of the
record is performed using a specified key
, whose value
is derived from an
expression. The resulting record is exposed in an object whose location is
specified by the target
expression. If a matching record cannot be found,
then the resulting object is empty.
The retrieval of the record is performed lazily; it does not occur until the
first attempt to access a value in the target
. This defers the overhead of
file operations and text processing until a value is first required. This also
means that the value expression is not evaluated until the object is first
accessed.
Usage
{
"name": string,
"type": "FileAttributesFilter",
"config": {
"file": configuration expression<string>,
"charset": configuration expression<string>,
"separator": configuration expression<enumeration>,
"header": configuration expression<boolean>,
"fields": [ configuration expression<string>, ... ],
"target": lvalue-expression,
"key": configuration expression<string>,
"value": runtime expression<string>

Unix-style colon-separated values, with backslash as the escape character.
COMMA
-
Comma-separated values, with support for quoted literal strings.
TAB
-
Tab-separated values, with support for quoted literal strings.
Default:
COMMA
"header"
: configuration expression<boolean>,optional-
A flag to treat the first row of the file as a header row.
When the first row of the file is treated as a header row, the data in that row is disregarded and cannot be returned by a lookup operation.
Default:

. "fields"
: array of configuration expression<strings>, optional-
A list of keys in the order they appear in a record.
If
fields
is not set, the keys are assigned automatically by the column numbers of the file. "target"

Expression that yields the target object to contain the record.
The target object is a
Map<String, String>
, where the fields are the keys. For example, if the target is${attributes.file}
and the record has ausername
field and apassword
field mentioned in the fields list, Then you can access the user name as${attributes.file.username}
and the password as${attributes.file.password}
.See also Expressions.
"key"

ForwardedRequestFilter
Rebase the request URI to a computed scheme, host name, and port.
Use this filter to configure redirects when a request is forwarded by an upstream application such as a TLS offloader.
Usage
{
"name": string,
"type": "ForwardedRequestFilter",

Example
In the following configuration, IG runs behind an AWS load balancer, to perform a login page redirect to an authentication party, using the original URI requested by the client.
IG can access the URI used by the load balancer to reach IG, but can’t access the original request URI.
The load balancer breaks the original request URI into the following headers, and adds them to the incoming request:
-
X-Forwarded-Proto
: Scheme -
X-Forwarded-Port
: Port -
Host
: Original host name, and possibly the port.
{
"type": "ForwardedRequestFilter",
"config": {
"scheme": "${request.headers['X-Forwarded-Proto'][0]}",
"host": "${split(request.headers['Host'][0], ':')[0]}",
"port": "${integer(request.headers['X-Forwarded-Port'][0])}"
}
}
HeaderFilter
Removes headers from and adds headers to request and response messages. Headers are added to any existing headers in the message. To replace a header, remove the header and then add it again.

"messageType": configuration expression<enumeration>,
"remove": [ configuration expression<string>, ... ],
"add": {
string: [ runtime expression<string>, ... ], ...
}
}
}

or"RESPONSE"
. "remove"
: array of configuration expression<strings>, optional-
The names of header fields to remove from the message.
"add"
: object, optional-
One or more headers to add to a request, with the format
name: [ value, … ]
, where:-
name is a string for a header name.
-
value is a runtime expression that resolves to one or more header values.
-
Examples
Replace host header on an incoming request
The following example replaces the host header on the incoming request with the
value myhost.com
:
{
"name": "ReplaceHostFilter",
"type": "HeaderFilter",
"config": {
"messageType": "REQUEST",
"remove": [ "host" ],
"add": {
"host": [ "myhost.com" ]
}
}
}
Add a header to a response
The following example adds a Set-Cookie
header to the response:
{
"name": "SetCookieFilter",
"type": "HeaderFilter",
"config": {
"messageType": "RESPONSE",
"add": {
"Set-Cookie": [ "mysession=12345" ]
}
}
}
Add headers to a request
The following example adds the headers custom1
and custom2
to the request:
{
"name": "SetCustomHeaders",
"type": "HeaderFilter",
"config": {
"messageType": "REQUEST",
"add": {
"custom1": [ "12345", "6789" ],
"custom2": [ "abcd" ]
}
}
}
Add a token value to a response
The following example adds the value of session’s policy enforcement token to
the pef_sso_token
header in the response:
{
"type": "HeaderFilter",
"config": {
"messageType": "RESPONSE",
"add": {
"pef_sso_token": ["${session.pef_token}"]
}
}
}
Add headers and logging results
The following example adds a message to the request and response as it passes
through the Chain, and the capture
on the ReverseProxyHandler logs the
result. With IG and the sample application set up as described in
the Getting started, access this route on
http://ig.example.com:8080/home/chain.
{
"condition": "${find(request.uri.path, '^/home/chain')}",
"handler": {
"type": "Chain",
"comment": "Base configuration defines the capture decorator",
"config": {
"filters": [
{
"type": "HeaderFilter",
"comment": "Add a header to all requests",
"config": {
"messageType": "REQUEST",
"add": {
"MyHeaderFilter_request": [
"Added by HeaderFilter to request"
]
}
}
},
{
"type": "HeaderFilter",
"comment": "Add a header to all responses",
"config": {
"messageType": "RESPONSE",
"add": {
"MyHeaderFilter_response": [
"Added by HeaderFilter to response"
]
}
}
}
],
"handler": {
"type": "ReverseProxyHandler",
"comment": "Log request, pass it to the sample app, log response",
"capture": "all",
"baseURI": "http://app.example.com:8081"
}
}
}
}
The chain receives the request and context and processes it as follows:
-
The first
HeaderFilter
adds a header to the incoming request. -
The second
HeaderFilter
manages responses not requests, so it simply passes the request and context to the handler. -
The
ReverseProxyHandler
captures (logs) the request. -
The
ReverseProxyHandler
forwards the transformed request to the protected application. -
The protected application passes a response to the
ReverseProxyHandler
. -
The
ReverseProxyHandler
captures (logs) the response. -
The second
HeaderFilter
adds a header added to the response. -
The first
HeaderFilter
is configured to manage requests, not responses, so it simply passes the response back to IG.
The following example lists some of the HTTP requests and responses captured
as they flow through the chain. You can search the log files for
MyHeaderFilter_request
and MyHeaderFilter_response
.
# Original request from user-agent
GET http://ig.example.com:8080/home/chain HTTP/1.1
Accept: /
Host: ig.example.com:8080
# Add a header to the request (inside IG) and direct it to the protected application
GET http://app.example.com:8081/home/chain HTTP/1.1
Accept: /
Host: ig.example.com:8080
MyHeaderFilter_request: Added by HeaderFilter to request
# Return the response to the user-agent
HTTP/1.1 200 OK
Content-Length: 1809
Content-Type: text/html; charset=ISO-8859-1
# Add a header to the response (inside IG)
HTTP/1.1 200 OK
Content-Length: 1809
MyHeaderFilter_response: Added by HeaderFilter to response
HttpBasicAuthenticationClientFilter
Authenticates clients according to the HTTP basic access authentication scheme.
HTTP basic access authentication is a simple challenge and response mechanism,
where a server requests credentials from a client, and the client passes them
to the server in an Authorization
header. The credentials are base-64 encoded.
To protect them, use SSL encryption for the connections between the server and
client. For more information, refer to
RFC 2617.
Compare the purpose of this filter with that of the following filters:
|
Use HttpBasicAuthenticationClientFilter in a service-to-service context, where services need to access resources protected by HTTP basic access authentication.
Usage
{
"name": string,
"type": "HttpBasicAuthenticationClientFilter",
"config": {
"username": configuration expression<string>,
"passwordSecretId": configuration expression<secret-id>,
"secretsProvider": SecretsProvider reference,
"urlEncodeCredentials": configuration expression<boolean>
}
}
Properties
"username"
: configuration expression<string>, required-
The username of the client to authenticate.
"passwordSecretId"
: configuration expression<string>, required-
The secret ID required to obtain the client password.
This secret ID must point to a
GenericSecret
. "secretsProvider"
: SecretsProvider reference, required-
The SecretsProvider to use to obtain the
passwordSecretId
. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline. "urlEncodeCredentials"
: configuration expression<boolean>, optional-
Set to
true
to URL-encoded credentials before base64-encoding them.Default:
false
Example
The following example shows the flow of information when a client service accesses a resource protected by HTTP basic access authentication:
-
Add the following script to the IG configuration:
$HOME/.openig/scripts/groovy/BasicAuthResourceServerFilter.groovy
appdata\OpenIG\scripts\groovy\BasicAuthResourceServerFilter.groovy
/* * This script is a simple implementation of HTTP basic access authentication on * server side. * It expects the following arguments: * - realm: the realm to display when the user agent prompts for * username and password if none were provided. * - username: the expected username * - passwordSecretId: the secretId to find the password * - secretsProvider: the SecretsProvider to query for the password */ import static org.forgerock.util.promise.Promises.newResultPromise; import java.nio.charset.Charset; import org.forgerock.util.encode.Base64; import org.forgerock.secrets.Purpose; import org.forgerock.secrets.GenericSecret; String authorizationHeader = request.getHeaders().getFirst("Authorization"); if (authorizationHeader == null) { // No credentials provided, return 401 Unauthorized Response response = new Response(Status.UNAUTHORIZED); response.getHeaders().put("WWW-Authenticate", "Basic realm=\"" + realm + "\""); return newResultPromise(response); } return secretsProvider.getNamed(Purpose.PASSWORD, passwordSecretId) .thenAsync(password -> { // Build basic authentication string -> username:password StringBuilder basicAuthString = new StringBuilder(username).append(":"); password.revealAsUtf8{ p -> basicAuthString.append(new String(p).trim()) }; String expectedAuthorization = "Basic " + Base64.encode(basicAuthString.toString().getBytes(Charset.defaultCharset())); // Incorrect credentials provided, return 403 forbidden if (!expectedAuthorization.equals(authorizationHeader)) { return newResultPromise(new Response(Status.FORBIDDEN)); } // Correct credentials provided, continue. return next.handle(context, request); }, noSuchSecretException -> { throw new RuntimeException(noSuchSecretException); });
The script is a simple implementation of the HTTP basic access authentication scheme. For information about scripting filters and handlers, refer to Extensibility.
-
Add the following route to IG:
$HOME/.openig/config/routes/http-basic-access.json
appdata\OpenIG\config\routes\http-basic-access.json
{ "name": "http-basic-access", "baseURI": "http://ig.example.com:8080", "condition" : "${find(request.uri.path, '^/http-basic-access')}", "heap": [ { "name": "httpBasicAuthEnabledClientHandler", "type": "Chain", "capture": "all", "config": { "filters": [ { "type": "HttpBasicAuthenticationClientFilter", "config": { "username": "myclient", "passwordSecretId": "password.secret.id", "secretsProvider": { "type": "Base64EncodedSecretStore", "config": { "secrets": { "password.secret.id": "cGFzc3dvcmQ=" } } } } } ], "handler": "ForgeRockClientHandler" } } ], "handler": { "type": "ScriptableHandler", "config": { "type": "application/x-groovy", "clientHandler": "httpBasicAuthEnabledClientHandler", "source": [ "request.uri.path = '/http-basic-protected-resource'", "return http.send(context, request);" ] } } }
Note the following features of the route:
-
The route matches requests to
/http-basic-access
. -
The ScriptableHandler rewrites the request to target it to
/http-basic-protected-resource
, and then calls the HTTP client, that has been redefined to use the httpBasicAuthEnabledClientHandler. -
The httpBasicAuthEnabledClientHandler calls the HttpBasicAuthenticationClientFilter to authenticate the client, using the client’s credentials.
-
-
Add the following route to IG:
$HOME/.openig/config/routes/http-basic-protected-resource.json
appdata\OpenIG\config\routes\http-basic-protected-resource.json
{ "heap": [ { "name": "mySecretsProvider", "type": "Base64EncodedSecretStore", "config": { "secrets": { "password.secret.id": "cGFzc3dvcmQ=" } } } ], "name": "http-basic-protected-resource", "condition": "${find(request.uri.path, '^/http-basic-protected-resource')}", "handler": { "type": "Chain", "config": { "filters": [ { "name": "HttpBasicAuthResourceServerFilter", "type": "ScriptableFilter", "config": { "type": "application/x-groovy", "file": "BasicAuthResourceServerFilter.groovy", "args": { "realm": "IG Protected Area", "username": "myclient", "passwordSecretId": "password.secret.id", "secretsProvider": "${heap['mySecretsProvider']}" } } } ], "handler": { "type": "StaticResponseHandler", "config": { "status": 200, "headers": { "Content-Type": [ "text/html; charset=UTF-8" ] }, "entity": "<html><body><h2>Access Granted</h2></body></html>" } } } } }
Notice the following features of the route:
-
The route matches requests to
/http-basic-protected-resource
. -
The ScriptableFilter provides a script to implement a simple HTTP basic access authentication scheme, that compares the provided credentials with the expected credentials.
-
When the client is authenticated, the StaticResponseHandler returns a message that access is granted.
-
-
Access the route on http://ig.example.com:8080/http-basic-access.
Because the expected credentials were provided in the request, a message shows that access is granted.
HttpBasicAuthFilter
Authenticate clients by providing the client credentials as a basic authorization header in the request. The credentials are base64-encoded.
This filter performs HTTP basic access authentication, described in RFC 2617.
Use this filter primarily for password replay scenarios, where the password is stored externally in clear text.
If challenged for authentication via a 401 Unauthorized
status code by the
server, this filter retries the request with credentials attached. After an HTTP
authentication challenge is issued from the remote server, all subsequent
requests to that remote server that pass through the filter include the user
credentials.
If authentication fails (including the case where no credentials are yielded from expressions), then processing is diverted to the specified authentication failure handler.
Usage
{
"name": string,
"type": "HttpBasicAuthFilter",
"config": {
"username": runtime expression<string>,
"password": runtime expression<string>,
"failureHandler": Handler reference,
"cacheHeader": configuration expression<boolean>
}
}
Properties
"username"
: runtime expression<string>, required-
The username to supply during authentication.
See also Expressions.
"password"
: runtime expression<string>, required-
The password to supply during authentication.
See also Expressions.
"failureHandler"
: Handler reference, required-
Dispatch to this Handler if authentication fails.
Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object.
See also Handlers.
"cacheHeader"
: configuration expression<boolean>,optional-
Whether or not to cache credentials in the session after the first successful authentication, and then replay those credentials for subsequent authentications in the same session.
With
"cacheHeader": false
, the filter generates the header for each request. This is useful, for example, when users change their passwords during a browser session.Default:
true
Example
{
"name": "MyAuthenticator",
"type": "HttpBasicAuthFilter",
"config": {
"username": "demo",
"password": "password",
"failureHandler": "AuthFailureHandler",
"cacheHeader": false
}
}
IdTokenValidationFilter
Validates an ID token by checking the standard claims, aud
, exp
, and
iat
. If specified in the configuration, this filter also checks the
ID token issuer and signature.
This filter passes data into the context as follows:
-
If the JWT is validated, the request continues down the chain. The data is provided in the JwtValidationContext.
-
If the JWT is not validated, data is provided in the JwtValidationErrorContext.
If a failure handler is configured, the request passes to the failure handler. Otherwise, an HTTP 403 Forbidden is returned.
The iat
claim is required, and the iat
minus the skewAllowance
must be
before the current time on the IG clock. For information, see
OpenID Connect Core 1.0 incorporating errata set 1.
Usage
{
"name": string,
"type": "IdTokenValidationFilter",
"config": {
"idToken": runtime expression<string>,
"audience": configuration expression<string>,
"issuer": configuration expression<string>,
"skewAllowance": configuration expression<duration>,
"verificationSecretId": configuration expression<secret-id>,
"secretsProvider": SecretsProvider reference,
"customizer": JwtValidatorCustomizer reference,
"failureHandler": Handler reference
}
}
Properties
"idToken"
: runtime expression<string>, required-
The ID token as an expression representing the JWT or signed JWT in the request. Cannot be null.
"audience"
: configuration expression<string>, required-
One
aud
claim to check on the JWT. Cannot be null. "issuer"
: configuration expression<string>, optional-
One
iss
claim to check on the JWT. Can be null.
"skewAllowance"
: configuration expression<duration>, optional-
The duration to add to the validity period of a JWT to allow for clock skew between different servers. To support a zero-trust policy, the skew allowance is by default zero.
A
skewAllowance
of 2 minutes affects the validity period as follows:-
A JWT with an
iat
of 12:00 is valid from 11:58 on the IG clock. -
A JWT with an
exp
13:00 is expired after 13:02 on the IG clock.
Default:
zero
-
"verificationSecretId"
: configuration expression<secret-id>, required to verify the signature of signed tokens-
The secret ID for the secret to verify the signature of signed tokens.
This secret ID must point to a
CryptoKey
.If configured, the token must be signed. If not configured, IG does not verify the signature.
For information about how signatures are validated, refer to Validating the signature of signed tokens. For information about how each type of secret store resolves named secrets, refer to Secrets.
"secretsProvider"
: SecretsProvider reference, required-
The SecretsProvider to use to resolve queried secrets, such as passwords and cryptographic keys. Provide either the name of a SecretsProvider object defined in the heap, or specify a SecretsProvider object inline.
"customizer"
: JwtValidatorCustomizer reference, optional-
A set of validation constraints for JWT claims and sub-claims. If a claim is not validated against the constraint, the JWT is not validated.
The customizer does not override existing constraints, such as
aud
,iss
,exp
, andiat
, which are predefined in the IdTokenValidationFilter, Defining a new constraint on an already constrained claim has an impact only if the new constraint is more restrictive.JwtValidatorCustomizer provides a ScriptableJwtValidatorCustomizer to enrich a
builder
object by using its methods. Get more information about the following items:-
The
builder
object, at Available Objects. -

{ "name": "idtokenvalidation", "condition": "${find(request.uri.path, '^/idtokenvalidation')}", "capture": "all", "handler": { "type": "Chain", "config": { "filters": [{ "type": "IdTokenValidationFilter", "config": { "idToken": "<id_token_value>", "audience": "client-application", "issuer": "http://am.example.com:8088/openam/oauth2", "failureHandler": { "type": "ScriptableHandler", "config": { "type": "application/x-groovy", "source": [ "def response = new Response(Status.FORBIDDEN)", "response.headers['Content-Type'] = 'text/html; charset=utf-8'", "def errors = contexts.jwtValidationError.violations.collect{it.description}", "def display = \"<html>Can't validate id_token:<br> ${contexts.jwtValidationError.jwt} \"", "display <<=\"<br><br>For the following errors:<br> ${errors.join(\"<br>\")}</html>\"", "response.entity=display as String", "return response" ] } }, "verificationSecretId": "verify", "secretsProvider": { "type": "JwkSetSecretStore", "config": { "jwkUrl": "http://am.example.com:8088/openam/oauth2/connect/jwk_uri" } } } }], "handler": { "type": "StaticResponseHandler", "config": { "status": 200, "headers": { "Content-Type": [ "text/html; charset=UTF-8" ] }, "entity": "<html><body>Validated id_token:<br> ${contexts.jwtValidation.value}</body></html>" } } } } }
Notice the following features of the route:
-
The route matches requests to
/idtokenvalidation
. -
A SecretsProvider declares a JwkSetSecretStore to validate secrets for signed JWTs, which specifies the URL to a JWK set on AM that contains the signing keys.
-
The property
verificationSecretId
is configured with a value. If this property is not configured, the filter does not verify the signature of tokens. -
The JwkSetSecretStore specifies the URL to a JWK set on AM, that contains verification keys identified by a
kid
. The signature of the token is verified as follows:-
If the value of a
kid
in the JWK set matches akid
in the the signed JWT, the JwkSetSecretStore verifies the signature. -
If the JWT doesn’t have a
kid
, or if the JWK set doesn’t contain a key with the same value, the JwkSetSecretStore looks for valid secrets with the same purpose as the value ofverificationSecretId
.
-
-
If the filter validates the token, the StaticResponseHandler displays the token value from the context
${contexts.jwtValidation.value}
. Otherwise, the ScriptableHandler displays the token value and a list of violations from the context${contexts.jwtValidationError.violations}
-
-
-
Test the setup:
-
In a terminal window, use a
curl
command similar to the following to retrieve an id_token:$ curl -s \ --user "client-application:password" \ --data "grant_type=password&username=demo&password=Ch4ng31t&scope=openid" \ http://am.example.com:8088/openam/oauth2/access_token { "access_token":"...", "scope":"openid", "id_token":"...", "token_type":"Bearer", "expires_in":3599 }
-
In the route, replace
<id_token_value>
with the value of theid_token
returned in the previous step.
-
-
Access the route on http://ig.example.com:8080/idtokenvalidation.
The validated token is displayed.
-
In the route, invalidate the token by changing the value of the audience or issuer, and then access the route again.
The value of the token, and the reasons that the token is invalid, are displayed.
-
-
JwtBuilderFilter
Collects data at runtime, packs it in a JSON Web Token (JWT), and places the resulting JWT into the JwtBuilderContext.
Configure JwtBuilderFilter to create an unsigned JWT, a signed JWT, a signed then encrypted JWT, or an encrypted JTW:
-
Sign the JWT so that an application can validate the authenticity of the claims/data. The JWT can be signed with a shared secret or private key, and verified with a shared secret or corresponding public key.
-
Encrypt the JWT to reduce the risk of a data breach.
For a flexible way to pass identity or other runtime information to the protected application, use this filter with a HeaderFilter.
To enable downstream filters and handlers to verify signed and/or encrypted JWTs built by this filter, use this filter with a JwkSetHandler.
Usage
{
"name": string,
"type": "JwtBuilderFilter",
"config": {
"template": map or runtime expression<map>,
"secretsProvider": SecretsProvider reference,
"signature": object,
"encryption": object
}
}
Properties
"template"
: map or runtime expression<map>, required-
A map of one or more data pairs with the format

-
The value is a data object, or a runtime expression that evaluates to a data object
The following formats are allowed:
{ "template": { "string": "runtime expression<object>", ... } }
{ "template": "runtime expression<map>" }
In the following example, the property is a map whose values are runtime expressions that evaluate to objects in the context:
{ "template": { "name": "${contexts.userProfile.commonName}", "email": "${contexts.userProfile.rawInfo.mail[0]}", "address": "${contexts.userProfile.rawInfo.postalAddress[0]}", "phone": "${contexts.userProfile.rawInfo.telephoneNumber[0]}" } }
In the following example, the property is a runtime expression that evaluates to a map with the format
Map<String, Object>
:{ "template": "${contexts.attributes}" }
Use the
now
dynamic binding to dynamically set the value of an attribute that represents time. For example, set the value of attributes to a defined time after the expressions are evaluated, as follows:{ "name": "JwtBuilderFilter-1", "type": "JwtBuilderFilter", "config": { "template": { "iat": "${now.epochSeconds}", "nbf": "${now.plusSeconds(10).epochSeconds}", "exp": "${now.plusSeconds(20).epochSeconds}" }, "secretsProvider": "FileSystemSecretStore-1", "signature": { "secretId": "id.key.for.signing.jwt", "algorithm": "RS512" } } }

JwtValidationFilter
Validates an unsigned, signed, encrypted, or signed and encrypted JWT. The order of signing and encryption is not important; a JWT can be signed and then encrypted, or encrypted and then signed.
If the JWT is validated, the request continues down the chain. The data is provided in the JwtValidationContext.
If the JWT is not validated, data is provided in the JwtValidationErrorContext. If a failure handler is configured, the request passes to the failure handler. Otherwise, an HTTP 403 Forbidden is returned.

LocationHeaderFilter
For a response that generates a redirect to the proxied application, this filter rewrites the Location header on the response to redirect the user to IG.
Usage
{
"name": string,
"type": "LocationHeaderFilter",
"config": {
"baseURI": runtime expression<url>
}
}
An alternative value for type is RedirectFilter.
Properties
"baseURI"
: runtime expression<url>,optional-
The base URI of the IG instance. This is used to rewrite the Location header on the response.
The result of the expression must be a string that represents a valid URI, but is not a real
java.net.URI
object. For example, it would be incorrect to use${request.uri}
, which is not a String but a MutableUri.Default: Redirect to the original URI specified in the request.
See also Expressions.
Example
In the following example, IG listens on https://ig.example.com:443
and the application it protects listens on http://app.example.com:8081
. The
filter rewrites redirects that would normally take the user to locations under
http://app.example.com:8081
to go instead to locations under
https://ig.example.com:443
.
{
"name": "LocationRewriter",
"type": "LocationHeaderFilter",
"config": {
"baseURI": "https://ig.example.com:443/"
}
}
OAuth2ClientFilter
In IG 7.2, this filter was renamed to AuthorizationCodeOAuth2ClientFilter.
For backward compatibility, the name OAuth2ClientFilter can still be used in routes in this release. However, to prevent problems in future releases, update your configuration as soon as possible.
OAuth2ResourceServerFilter
Validates a request containing an OAuth 2.0 access token. The filter expects an
OAuth 2.0 token from the HTTP Authorization header of the request, such as the
following example header, where the OAuth 2.0 access token is 1fc…ec9
:
Authorization: Bearer 1fc...ec9
The filter performs the following tasks:
-
Extracts the access token from the request header.
-
Uses the configured access token resolver to resolve the access token against an authorization server, and validate the token claims.
-
Checks that the token has the scopes required by the filter configuration.
-
Injects the access token info into the OAuth2Context.
The following errors can occur during access token validation:
Error | Response from the filter to the user agent |
---|---|
Combination of the filter configuration and access token result in an invalid request to the authorization server. |
|
There is no access token in the request header. |
|
The access token isn’t valid, for example, because it has expired. |
|
The access token doesn’t have all of the scopes required in the OAuth2ResourceServerFilter configuration. |
|
Usage
{
"name": string,
"type": "OAuth2ResourceServerFilter",
"config": {
"accessTokenResolver": AccessTokenResolver reference,
"cache": object,
"executor": Executor service reference,
"requireHttps": configuration expression<boolean>,
"realm": configuration expression<string>,
"scopes": [ runtime expression<string>, ... ] or ScriptableResourceAccess reference
}
}
An alternative value for type is OAuth2RSFilter.
Properties
"accessTokenResolver"
: AccessTokenResolver reference, required-
Resolves an access token against an authorization server. Configure one of the following access token resolvers:
To decorate an AccessTokenResolver, add the decoration at the
accessTokenResolver
level. The following example uses the default timer decorator to record the time that a TokenIntrospectionAccessTokenResolver takes to process a request:{ "accessTokenResolver": { "type": "TokenIntrospectionAccessTokenResolver", "config": { ... }, "timer": true } }
"cache"
: object, optional-
Configuration of caching for OAuth 2.0 access tokens. By default, access tokens are not cached. For an alternative way of caching of OAuth 2.0 access tokens, configure CacheAccessTokenResolver.
When an access token is cached, IG can reuse the token information without repeatedly asking the authorization server to verify the access token. When caching is disabled, IG must ask the authorization server to verify the access token for each request.
(From AM 6.5.3.) When an access_token is revoked on AM, the CacheAccessTokenResolver can delete the token from the cache when both of the following conditions are true:
-
The
notification
property of AmService is enabled. -
The delegate AccessTokenResolver provides the token metadata required to update the cache.
When a refresh_token is revoked on AM, all associated access tokens are automatically and immediately revoked.
"cache": { "enabled": configuration expression<boolean>, "defaultTimeout": configuration expression<duration>, "maxTimeout": configuration expression<duration>, "amService": AmService reference, "onNotificationDisconnection": configuration expression<enumeration> }
enabled
: configuration expression<boolean>, optional-
Enable or disable caching.
Default:
false
defaultTimeout
: configuration expression<duration>, optional-
The duration for which to cache an OAuth 2.0 access token if it doesn’t provide a valid expiry value.
If an access token provides an expiry value that falls before the current time plus the
maxTimeout
, IG uses the token expiry value.The following example caches access tokens for these times:
-
One hour, if the access token doesn’t provide a valid expiry value.
-
The duration specified by the token expiry value, when the token expiry value is shorter than one day.
-
One day, when the token expiry value is longer than one day.
"cache": { "enabled": true, "defaultTimeout": "1 hour", "maxTimeout": "1 day" }
Default:
1 minute
-
maxTimeout
: configuration expression<duration>, optional-
The maximum duration for which to cache OAuth 2.0 access tokens.
If an access token provides an expiry value that falls after the current time plus the
maxTimeout
, IG uses themaxTimeout
.The duration cannot be
zero
orunlimited
. "amService"
: AmService reference, optional-
(From AM 6.5.3.) The AmService to use for the WebSocket notification service. To evict revoked access tokens from the cache, enable the
notifications
property of AmService. onNotificationDisconnection
: configuration expression<enumeration>, optional-
An
amService
must be configured for this property to have effect.The strategy to manage the cache when the WebSocket notification service is disconnected, and IG receives no notifications for AM events. If the cache is not cleared it can become outdated, and IG can allow requests on revoked sessions or tokens.
Cached entries that expire naturally while the notification service is disconnected are removed from the cache.
Use one of the following values:
-
NEVER_CLEAR
-
When the notification service is disconnected:
-
Continue to use the existing cache.
-
Deny access for requests that are not cached, but do not update the cache with these requests.
-
-
When the notification service is reconnected:
-
Continue to use the existing cache.
-
Query AM for incoming requests that are not found in the cache, and update the cache with these requests.
-
-
-
CLEAR_ON_DISCONNECT
-
When the notification service is disconnected:
-
Clear the cache.
-
Deny access to all requests, but do not update the cache with these requests.
-
-
When the notification service is reconnected:
-
Query AM for all requests that are not found in the cache. (Because the cache was cleared, the cache is empty after reconnection.)
-
Update the cache with these requests.
-
-
-
CLEAR_ON_RECONNECT
-
When the notification service is disconnected:
-
Continue to use the existing cache.
-
Deny access for requests that are not cached, but do not update the cache with these requests.
-
-
When the notification service is reconnected:
-
Query AM for all requests that are not found in the cache. (Because the cache was cleared, the cache is empty after reconnection.)
-
Update the cache with these requests.

in UriRouterContext) uses the HTTPS scheme.If the received request does not use HTTPS, it is rejected.
Default: true.
"realm"
: configuration expression<string>, optional-
HTTP authentication realm to include in the WWW-Authenticate response header field when returning an HTTP 401 Unauthorized status to a user agent that need to authenticate.
Default: IG
"scopes"
: array of runtime expression<strings> or ScriptableResourceAccess <reference>, required-
A list of one of more scopes required by the OAuth 2.0 access token.
- array of runtime expression<strings>, required if ScriptableResourceAccess is not used
-
A string, array of strings, runtime expression<string>, or array of runtime expression<string> to represent one or more scopes.
- ScriptableResourceAccess <reference>, required if "array of runtime expression<strings>" is not used
-
A script that produces a list of one or more scopes.
The script evaluates each request dynamically and returns the scopes that request needs to access the protected resource. The script must return a
Promise<Set, ResponseException>
or a `Set<String>.For information about the properties of ScriptableResourceAccess, refer to Scripts.
{ "name": string, "type": "ScriptableResourceAccess", "config": { "type": configuration expression<string>, "file": configuration expression<string>, // Use either "file" "source": [ string, ... ], // or "source", but not both. "args": object, "clientHandler": Handler reference } }
Default: Empty
Examples
For examples using OAuth2ResourceServerFilter, see Act as an OAuth 2.0 resource server.
OAuth2TokenExchangeFilter
Identifies a client’s access token or ID token (a subject token), and communicates with an authorization service, such as AM, to exchange it for a new token (an issued token):
-
When the OAuth2TokenExchangeFilter succesfully exchanges a token, it injects the issued token and its scopes into the OAuth2TokenExchangeContext.
-
When the OAuth2TokenExchangeFilter fails to exchange a token, it injects information about the failure into the OAuth2FailureContext, which is provided to the
failureHandler
.
The scopes for issued token can be restricted or expanded by the authorization services:
-
Restricted when the token scopes are a subset of those available to the subject token.
-
Expanded when they have scopes that are not included in the subject token.
Use this filter in the impersonation use case. For more information, refer to Token Exchange in AM’s OAuth 2.0 guide.

PasswordReplayFilter
Extracts credentials from AM and replays them to a login page or to the next filter or handler in the chain. The PasswordReplayFilter does not retry failed authentication attempts.
The PasswordReplayFilter filter uses the AM Post Authentication Plugin
Do not use the PasswordReplayFilter with AM authentication trees. |

The HTTP request message that replays the credentials.
{ "request": object, "method": config expression<string>, "uri": runtime expression<string>, "version": configuration expression<string>, "entity": runtime expression<string>, "headers": map, "form": map }
For information about the properties of `request`refer to Request.
The JSON object of
request
is theconfig
content of a StaticRequestFilter. "loginPage"
: runtime expression<boolean>, required unlessloginPageContentMarker
is defined-
true
: Direct the request to a login page, extract credentials, and replay them.false
: Pass the request unchanged to the next filter or handler in the chain.The following example expression resolves to
true
when the request is an HTTP GET, and the request URI path is/login
:${find(request.uri.path, '/login') and (request.method == 'GET')}
"loginPageContentMarker"
: pattern, required unlessloginPage
is defined-
A pattern that matches when a response entity is a login page.
For an example route that uses this property, refer to Login form with password replay and cookie filters.
See also Patterns.
"credentials"
: Filter reference, optional-
Filter that injects credentials, making them available for replay. Consider using a
FileAttributesFilter
or anSqlAttributesFilter
.When this is not specified, credentials must be made available to the request by other means.

: array of <objects>, optional-
Objects to extract values from the login page entity.
{ "loginPageExtractions": [ { "name": string, "pattern": pattern }, ... ] }
For an example route that uses this property, refer to Login which requires a hidden value from the login page.
The extract configuration array is a series of configuration objects. To extract multiple values, use multiple extract configuration objects. Each object has the following fields:
"name"
: string, required-
Name of the field where the extracted value is put.
The names are mapped into
attributes.extracted

is reserved to hold a boolean that indicates whether the response entity is a login page. "pattern"
: pattern, required-
The regular expression pattern to find in the entity.
The pattern must contain one capturing group. (If it contains more than one, only the value matching the first group is placed into
attributes.extracted
.)For example, suppose the login page entity contains a nonce required to authenticate, and the nonce in the page looks like
nonce='n-0S6_WzA2Mj'
. To extractn-0S6_WzA2Mj
, set"pattern": " nonce='(.*)'"
.
Example
The following example authenticates requests using static credentials when the
request URI path is /login
. This PasswordReplayFilter example does not
include any mechanism for remembering when authentication has already been
successful, it simply replays the authentication every time that the request
URI path is /login
:
{
"handler": {
"type": "Chain",
"config": {
"filters": [{
"type": "PasswordReplayFilter",
"config": {
"loginPage": "${request.uri.path == '/login'}",
"request": {

}
}
}
}],
"handler": "ReverseProxyHandler"
}
}
}
For additional examples, refer to Configuration templates, and the Javadoc for the PasswordReplayFilter class.
PolicyEnforcementFilter
Requests policy decisions from AM, which allows or denies the request based on the request context, the request URI, and the AM policies.
For information about how IG enforces policy decisions from AM, refer to Policy enforcement.
Attributes and advices are stored in the policyDecision
context.
For information, refer to
PolicyDecisionContext.
IG responds to the following advice types from AM:
-
AuthLevel
: The minimum authentication level at which a user agent must authenticate to access a resource. -
AuthenticateToService
: The name of an authorization chain or service to which a user agent must authenticate to access a resource. -
AuthenticateToRealm
: The name of a realm to which a user agent must authenticate to access a resource. -
AuthScheme
: The name of an authentication module to which a user agent must authenticate to access a resource, the policy set name, and the authentication timeout. -
Transaction
: The additional actions that a user agent must perform before having a one-time access to the protected resource.
Notes on configuring policies in AM
In the AM policy, remember to configure the Resources
parameter with
the URI of the protected application.
The request URI from IG must match the Resources
parameter defined
in the AM policy. If the URI of the incoming request is changed before it
enters the policy filter (for example, by rebasing or scripting), remember to
change the Resources
parameter in AM policy accordingly.
WebSocket notifications for policy changes
When WebSocket notifications are set up for changes to policies, IG receives a notification from AM when a policy decision is created, deleted, or updated.
For information about setting up WebSocket notifications, using them to clear the policy cache, and including them in the server logs, refer to WebSocket Notifications.

,claimsSubject
-
The AM SSO or CDSSO token ID string for the subject making the request to the protected resource.
ssoTokenSubject
can take the following values:-
${contexts.ssoToken.value}
, when the SingleSignOnFilter is used for authentication -
${contexts.ssoToken.value}
or${contexts.cdsso.token}

Default: Policy decisions are not cached.
Policy decisions that contain advices are never cached. The following code example caches AM policy decisions without advices for these times:
-
One hour, when the policy decision doesn’t provide a
ttl
value. -
The duration specified by the
ttl
, whenttl
is shorter than one day. -

ttl
is longer than one day.
"cache": { "enabled": true, "defaultTimeout": "1 hour", "maximumTimeToCache": "1 day" }
enabled
: configuration expression<boolean>, optional-
Enable or disable caching of policy decisions.
When a policy decision is cached, IG can reuse the policy decision without repeatedly asking AM for a new policy decision. When caching is disabled, IG must ask AM to make a decision for each request.
Default:
false
defaultTimeout
: configuration expression<duration>, optional-
The default duration for which to cache AM policy decisions.
If an AM policy decision provides a valid
ttl
value to specify the time until which the policy decision remains valid, IG uses that value or themaxTimeout
.Default:
1 minute
"executor"
: Executor service reference, optional-
An executor service to schedule the execution of tasks, such as the eviction of entries in the cache.
Default:
ForkJoinPool.commonPool()

Default: Unlimited/unbound.
maximumTimeToCache
: configuration expression<duration>, optional-
The maximum duration for which to cache AM policy decisions.
If the
ttl
value provided by the AM policy decision is after the current time plus themaximumTimeToCache
, IG uses themaximumTimeToCache
.The duration cannot be
zero
orunlimited
. onNotificationDisconnection
: configuration expression<enumeration>, optional-
The strategy to manage the cache when the WebSocket notification service is disconnected, and IG receives no notifications for AM events. If the cache is not cleared it can become outdated, and IG can allow requests on revoked sessions or tokens.
Cached entries that expire naturally while the notification service is disconnected are removed from the cache.
Use one of the following values:
-
NEVER_CLEAR
-
When the notification service is disconnected:
-
Continue to use the existing cache.
-
Deny access for requests that are not cached, but do not update the cache with these requests.
-
-
When the notification service is reconnected:
-
Continue to use the existing cache.
-
Query AM for incoming requests that are not found in the cache, and update the cache with these requests.
-
-
-
CLEAR_ON_DISCONNECT
-
When the notification service is disconnected:
-
Clear the cache.
-
Deny access to all requests, but do not update the cache with these requests.
-
-
When the notification service is reconnected:
-
Query AM for all requests that are not found in the cache. (Because the cache was cleared, the cache is empty after reconnection.)
-
Update the cache with these requests.
-
-
-
CLEAR_ON_RECONNECT
-
When the notification service is disconnected:
-
Continue to use the existing cache.
-
Deny access for requests that are not cached, but do not update the cache with these requests.
-
-
When the notification service is reconnected:
-
Query AM for all requests that are not found in the cache. (Because the cache was cleared, the cache is empty after reconnection.)
-
Update the cache with these requests.
-
-
Default:
CLEAR_ON_DISCONNECT
-
-
"environment"
: map or runtime expression<map>, optional-
A map of one or more data pairs with the format
Map<String, Object>
, where:-
The key is the name of a field in the request environment or context, such as a request header
-
The value is the object to forward to AM with a policy decision request, or a runtime expression that evaluates to the object
The following formats are allowed:
{ "claimsSubject": { "string": "runtime expression<object>", ... } }
{ "claimsSubject": "runtime expression<map>" }
AM uses environment conditions to set the circumstances under which a policy applies. For example, environment conditions can specify that the policy applies only during working hours or only when accessing from a specific IP address.
Forward any HTTP header or any value that the AM policy definition can use.
In the following example, the property is a map whose values are runtime expressions that evaluate to request headers, an ID token, and the IP address of the subject making the request:
"environment": { "H-Via": "${request.headers['Via']}", "H-X-Forwarded-For": "${request.headers['X-Forwarded-For']}", "H-myHeader": "${request.headers['myHeader']}", "id_token": [ "${attributes.openid.id_token}" ], "IP": [ "${contexts.client.remoteAddress}" ] }
-
"failureHandler"
: Handler reference, optional-
Handler to treat the request if it is denied by the policy decision.
In the following example, the
failureHandler
is a chain with a scriptable filter. If there are some advices with the policy decision, the script recovers the advices for processing. Otherwise, it passes the request to theStaticResponseHandler
to display a message."failureHandler": { "type": "Chain", "config": { "filters": [ { "type": "ScriptableFilter", "config": { "type": "application/x-groovy", "source": [ "if (contexts.policyDecision.advices['MyCustomAdvice'] != null) {", " return handleCustomAdvice(context, request)", "} else {", " return next.handle(context, request)", "}" ] } } ], "handler": { "type": "StaticResponseHandler", "config": { "status": 403, "headers": { "Content-Type": [ "text/plain; charset=UTF-8" ] }, "entity": "Restricted area. You do not have sufficient privileges." } } } }
Provide an inline handler configuration object, or the name of a handler object declared in the heap. See also Handlers.
Default: HTTP 403 Forbidden, the request stops being executed.

Return the resource URL to include in policy decision requests to AM. Configure one of the following ResourceUriProviders inline or in the heap:
-
RequestResourceUriProvider
-
ScriptableResourceUriProvider
Default:
RequestResourceUriProvider
RequestResourceUriProvider
-
Return a resource URL to include in policy decision requests to AM, by using the original URI of the request or the
baseURI
of the route."resourceUriProvider": { "type": "RequestResourceUriProvider", "config": { "useOriginalUri": configuration expression<boolean>, "includeQueryParams": configuration expression<boolean> } }
useOriginalUri
: configuration expression<boolean>, optional-
A flag to use the original URI of the request as the resource URL in policy decision requests to AM.
-
true
: Use the original URI of the request as the resource URL when requesting policy decisions from AM. -
false
: Use thebaseURI
of the route as the resource URL when requesting policy decisions from AM.
Default:
false
-
includeQueryParams
: configuration expression<boolean>, optional-
A flag to include query parameters in the resource URL when requesting policy decisions from AM:
-
true
: Include query parameters in the resource URL. For example, use the following URL with a query parameter:http://ig.example.com:8080/login?demo=capture
. -
false
: Exclude query parameters from the resource URL. For example, exclude the query parameter from the previous example:http://ig.example.com:8080/login
.
For AM policies that specify resource URLs without query parameters, use this option to reduce the amount of cached information.
Default:
true
-
ScriptableResourceUriProvider
-
Use a script to return a resource URL to include in policy decision requests to AM. The result of the script must be a string that represents the resource URL.
"resourceUriProvider": { "type": "ScriptableResourceUriProvider", "config": { "type": configuration expression<string>, "file": configuration expression<string>, // Use either "file" "source": [ string, ... ], // or "source", but not both. "args": object, "clientHandler": Handler reference } }
For information about these properties, see Scripts.
The following example script replaces existing query parameters with a single parameter:
"resourceUriProvider": { "type": "ScriptableResourceUriProvider", "config": { "type": "application/x-groovy", "source": [ "request.uri.setQuery('fromIG=true')", "return request.uri.toASCIIString()" ] } }
-
authenticateResponseRequestHeader
: configuration expression<string>, optional-
A header to include in a request to manage the way IG handles policy advices from AM. The header name and value is case-insensitive. The header value can be set as follows:
-
HEADER
: Return policy advices in aWWW-Authenticate
header as base64-encoded JSON in a parameter calledadvices
. -
Any other value: Return policy advices as parameters in a redirect response (default).
For information about how the header is used in policy enforcement, refer to Deny requests with advices in a header.
Default:
x-authenticate-response
-
useLegacyAdviceEncoding
: configuration expression<boolean>, optional-
The use of this property is deprecated and should be used only to support SDK in legacy installations. Refer to the Deprecated section of the Release Notes. -
True: Do not encode advices
-
False: Encode advices with the encoder used by the AM version
Default: False
-
Examples
For examples of policy enforcement, refer to Policy enforcement.
PrivateKeyJwtClientAuthenticationFilter
Supports client authentication with the private_key_jwt
client-assertion,
using an unencrypted JWT.
Clients send a signed JWT to the authorization server. IG builds and signs the JWT, and prepares the request as in the following example:
POST /token HTTP/1.1
Host: as.example.com
Content-Type: application/x-www-form-urlencoded
grant_type=authorization_code&
code=...&
client_id=<clientregistration_id>&
client_assertion_type=urn%3Aietf%3Aparams%3Aoauth%3Aclient-assertion-type%3Ajwt-bearer&
client_assertion=PHNhbWxwOl ... ZT
Use this filter with an endpoint handler that requires authentication with the
with the private_key_jwt
client-assertion, using an unencrypted JWT. For
example, the endpointHandler
handler in the
OAuth2TokenExchangeFilter.

ResourceOwnerOAuth2ClientFilter
This filter uses the Resource Owner Password Credentials grant type. According to information in the The OAuth 2.0 Authorization Framework, minimize use of this grant type and utilize other grant types whenever possible. Use this filter in a service-to-service context, where services need to access resources protected by OAuth 2.0. |
Authenticates OAuth 2.0 clients by using the resource owner’s OAuth 2.0 credentials to obtain an access token from an authorization server, and injecting the access token into the inbound request as a Bearer Authorization header.
Client authentication is provided by the endpointHandler

SamlFederationFilter
Initiates the login or logout of a SAML 2.0 Service Provider (SP) with a SAML 2.0 Identity Provider (IDP). Login is initiated for requests that do not:
-
Trigger a logout expression
-
Match a SAML endpoint
-
Include a valid session
Requests with a valid session are passed along the chain.
Usage
{
"name": string,
"type": "SamlFederationFilter",
"config": {
"redirectURI": configuration expression<url>,
"assertionMapping": map or configuration expression<map>,
"subjectMapping": configuration expression<string>,
"sessionIndexMapping": configuration expression<string>,
"authnContext": configuration expression<string>,
"authnContextDelimiter": configuration expression<string>,

"secretsProvider": SecretsProvider reference,
"spEntityId": configuration expression<string>,
"failureHandler": Handler reference
}
}
Properties
"redirectURI"
: configuration expression<url>, required-
The URI to use if there is no RelayState value.
"assertionMapping"
: map or configuration expression<map>, required-
A map with the format
Map<String, String>
, where:-
Key: Session name,
localName
-
Value: SAML assertion name,
incomingName
, or a configuration expression that evaluates to the name
The following formats are allowed:
{ "assertionMapping": { "string": "configuration expression<string>", ... } }
{ "assertionMapping": "configuration expression<map>" }
In the following example, the session names
username
andpassword
are mapped to SAML assertion namesmail
andmailPassword
:{ "assertionMapping": { "username": "mail", "password": "mailPassword" } }
If an incoming SAML assertion contains the following statement:
mail = demo@example.com mailPassword = demopassword
Then the following values are set in the session:
username[0] = demo@example.com password[0] = demopassword
For this to work, edit the
<Attribute name="attributeMap">
element in the SP extended metadata file,$HOME/.openig/SAML/sp-extended.xml
, so that it matches the assertion mapping configured in the SAML 2.0 Identity Provider (IDP) metadata.Because the dot character (
.
) serves as a query separator in expressions, do not use dot characters in the localName.To prevent different handlers from overwriting each others' data, use unique localName settings when protecting multiple service providers.
-
"subjectMapping"
: configuration expression<string>, optional-
Name of the session field to hold the value of the subject name. Because the dot character (
.
) serves as a query separator in expressions, do not use dot characters in the field name.Use this setting when protecting multiple service providers, as the different configurations must not map their data into the same fields of
session
. Otherwise different handlers can overwrite each others' data.As an example, if you set
"subjectMapping": "mySubjectName"
, then IG setssession.mySubjectName
to the subject name specified in the assertion. If the subject name is an opaque identifier, then this results in the session containing something like"mySubjectName": "vtO…zuL"
.Default: map to
session.subjectName
"sessionIndexMapping"
: configuration expression<string>, optional-
Name of the session field to hold the value of the session index. Because the dot character (
.
) serves as a query separator in expressions, do not use dot characters in the field name.Use this setting when protecting multiple service providers, as the different configurations must not map their data into the same fields of
session
. Otherwise different handlers can overwrite each others' data.As an example, if you set
"sessionIndexMapping": "mySessionIndex"
, then IG setssession.mySessionIndex
to the session index specified in the assertion. This results in the session containing something like"mySessionIndex": "s24c…801"
.Default: map to
session.sessionIndex
"authnContext"
: configuration expression<string>, optional-
Name of the session field to hold the value of the authentication context. Because the dot character (
.
) serves as a query separator in expressions, do not use dot characters in the field name.Use this setting when protecting multiple service providers, as the different configurations must not map their data into the same fields of
session
. Otherwise different handlers can overwrite each others' data.As an example, if you set
"authnContext": "myAuthnContext"
, then IG setssession.myAuthnContext
to the authentication context specified in the assertion. When the authentication context is password over protected transport, then this results in the session containing"myAuthnContext": "urn:oasis:names:tc:SAML:2.0:ac:classes:PasswordProtectedTransport"
.Default: map to
session.authnContext
"authnContextDelimiter"
: configuration expression<string>, optional-
The authentication context delimiter used when there are multiple authentication contexts in the assertion.
Default:
|
"assertionConsumerEndpoint"
: configuration expression<string>, optional-
Part of the URI that designates the consumer endpoint as defined in the SP metadata shared with the IDP.
If you modify this attribute, change the metadata to match.
Default:
fedletapplication
"SPinitiatedSSOEndpoint"
: configuration expression<string>, optional-
Part of the URI that designates the SP initiated SSO endpoint.
If you modify this attribute, change the metadata to match.
Default:
SPInitiatedSSO
"SPinitiatedSLOEndpoint"
: configuration expression<string>, optional-
Part of the URI that designates the SP initiated SLO endpoint.
If you modify this attribute, change the metadata to match.
Default:
SPInitiatedSLO
"singleLogoutEndpoint"
: configuration expression<string>, optional-
Part of the URI that designates the SP SLO endpoint as defined in the SP metadata shared with the IDP.
If you modify this attribute, change the metadata to match.
Default:
fedletSLORedirect
(same as the Fedlet) "singleLogoutEndpointSoap"
: configuration expression<string>, optional-
Part of the URI that designates the SP SLO SOAP endpoint as defined in the SPs metadata shared with the IDP.
If you modify this attribute, change the metadata to match.
Default:
fedletSloSoap
(same as the Fedlet) "useOriginalUri"
: configuration expression<boolean>, optional-
When
true
, use the original URI instead of a rebased URI to validate RelayState and Assertion Consumer Location URLs. Use this property if abaseUri
decorator is used in the route or inconfig.json
.Default:
true
"logoutExpression"
: runtime expression<boolean>, optional-
A flag to indicate whether a request initiates logout processing before reaching the protected application.
-
false
: The request does not initiate logout processing:-
If a valid SAML session is found, the request is forwarded to the protected application.
-
If a valid SAML session is not found, the request triggers the SAML login flow.
-
-
true
: The request initiates logout processing:-
If a valid SAML session is found, the request triggers the SAML logout flow:
-
If there is a RelayState URL parameter, the request is forwarded to that URL. RelayState provides backwards compatibility for SamlFederationHandler.
-
If there is no RelayState URL parameter and
logoutURI
is defined, the request is forwarded to the logout page. -
If there is no RelayState URL parameter and
logoutURI
is not defined, the request is forwarded to the protected application without any other validation.
-
-
If a valid session is not found, the request is forwarded to the protected application without any other validation.
-
To prevent unwanted access to the protected application, use
logoutExpression
with extreme caution as follows:-
Define a
logoutURI
. -
If you don’t define a
logoutURI
, specifylogoutExpression
to resolve totrue
only for requests that target dedicated logout pages of the protected application.
Consider the following examples when a
logoutURI
is not defined:-
This expression resolves to
true
only for requests with/app/logout
in their path:"logoutExpression": "${startsWith(request.uri.rawPath, '/app/logout')}"
When a request matches the expression, the SAML session is revoked and the request is forwarded to the
/app/logout
page. -
This expression resolves to
true
for all requests that containlogOff=true
in their query parameters:"logoutExpression": "${find(request.uri.query, 'logOff=true')}"
When a request matches the expression, the SAML session is revoked and the request is forwarded to the protected application without any other validation. In this example, an attacker can bypass IG’s security mechanisms by simply adding
?logOff=true
to a request.
Default:
${false}
-
"logoutURI"
: configuration expression<string>, optional-
The URL to which a request is redirected if
logoutExpression
is evaluated astrue
or when the protected application uses the single logout feature of the Identity Provider.Default: None, processing continues.
"secretsProvider"
: SecretsProvider reference, optional-
The SecretsProvider object to query for keys when AM provides signed or encrypted SAML assertions.
When this property is not set, the keys are provided by direct keystore look-ups based on entries in the SP extended metadata file,
sp-extended.xml
.For more information, refer to SecretsProvider.
"spEntityId"
: configuration expression<string>, optional-
The entity ID that this SP represents. Configure this property when more than one SP is defined in the metadata.
Default:
-
When no SPs are defined in the metadata an error is generated.
-
When there one SP defined in the metadata the filter uses that SP.
-
When there is more than one SP defined in the metadata the filter uses the first SP in the list of discovered metadata and logs a warning. Because ordering is not deterministic, the discovered SP can be the wrong SP.
-
"failureHandler"
: Handler reference, optional-
Handler to invoke when SAML processing fails.
Provide an inline handler configuration object, or the name of a handler object declared in the heap. See also Handlers.
Default: Return an error response containing a SAML processing error.
ScriptableFilter
Processes requests and responses by executing a Groovy script. Executed scripts must return one of the following:
To execute the next element in a chain (a filter or a handler), the script
must call the expression next.handle(context, request)
. If the script does not
call next.handle(context, request)
, the chain flow breaks and the script has
to build and return its own response by calling one of the following expressions:
-
return myResponse
-
return newResultPromise(myResponse)
Actions on the response returned from the downstream flow must be performed in the Promise’s callback methods.
For information about script properties, available global objects, and automatically imported classes, refer to Scripts. For information about creating scriptable objects in Studio, refer to Scripts in Studio and Configure scriptable throttling.
Usage
{
"name": string,
"type": "ScriptableFilter",
"config": {
"type": configuration expression<string>,
"file": configuration expression<string>, // Use either "file"
"source": [ string, ... ], // or "source", but not both.
"args": map,
"clientHandler": Handler reference
}
}
Properties
For information about properties for ScriptableFilter, refer to Scripts.
Examples
For an example scriptable filter that recovers policy advices from AM,
see the failureHandler
property of
PolicyEnforcementFilter.
SessionInfoFilter
Calls the AM endpoint for session information, and makes the data available as a new context to downstream IG filters and handlers. For information, refer to SessionInfoContext.
WebSocket notifications for sessions
When WebSocket notifications are set up for sessions, IG receives a
notification from AM when a user logs out of AM, or when the
AM session is modified, closed, or times out. IG then evicts
entries that are related to the event from the sessionCache
.
For information about setting up WebSocket notifications, using them to clear the session cache, and including them in the server logs, refer to WebSocket notifications.
Usage
{
"name": string,
"type": "SessionInfoFilter",
"config": {
"amService": AmService reference,
"ssoToken": runtime expression<string>
}
}
Properties
"amService"
: AmService reference, required-
The AmService object to use for communication with AM.
The following
sessionProperties
, are retrieved from AM:-
When
sessionProperties
in AmService is configured, listed session properties with a value. -
When
sessionProperties
in AmService is not configured, all session properties with a value. -
Properties with a value that are required by IG but not specified by
sessionProperties
in AmService. For example, when the session cache is enabled, session properties related to the cache are automatically retrieved.
Properties with a value are returned, properties with a null value are not returned.
-
"ssoToken"
: runtime expression<string>, optional-
Location of the AM SSO or CDSSO token.
This property can take the following values:
-
${contexts.ssoToken.value}
, when the SingleSignOnFilter is used for authentication -
${contexts.ssoToken.value}
or${contexts.cdsso.token}
, when the CrossDomainSingleSignOnFilter is used for authentication -
${request.headers['mySsoToken'][0]}
, where the SSO or CDSSO token is the first value of themySsoToken
header in the request.
Default:
${request.cookies['AmService-ssoTokenHeader'][0].value}
, whereAmService-ssoTokenHeader
is the name of the header or cookie where the AmService expects to find SSO or CDSSO tokens. -
Examples
For an example that uses the SessionInfoFilter, refer to Retrieve a Username From the sessionInfo Context.
SetCookieUpdateFilter
Updates the attribute values of Set-Cookie headers in a cookie. This filter facilitates the transition to the SameSite and secure cookie settings required by newer browsers. Use SetCookieUpdateFilter at the beginning of a chain to guarantee security along the chain.
Set-Cookie headers must conform to grammar in RFC 6265: Set-Cookie.
Usage
{
"name": string,
"type": "SetCookieUpdateFilter",
"config": {
"cookies": {
"cookie-name": {
"attribute-name": "attribute-value",
...
}
...
}
}
}
Properties
"cookies"
: map, required-
Configuration that matches case-sensitive cookie names to response cookies, and specifies how matching cookies attribute values should be updated. Each cookie begins with a name-value pair, where the value is one or more attribute-value pairs.
- cookie-name: pattern, required
-
The name of a cookie contained in the
Set-Cookie
header, as a pattern.To change the attribute value on all existing cookies, specify
.*
.If a cookie is named more than once, either explicitly or by the wildcard (
*
), the rules are applied to the cookie in the order they appear in the map.In the following example, the SameSite attribute of the CSRF cookie first takes the value
none
, and then that value is overwritten by the valueLAX
."cookies": { "CSRF": { "value": "myValue", "secure": ${true}, "SameSite": "none" } ".*": { "SameSite": "LAX" } }
- attribute-name: enumeration, required
-
A case-insensitive enumeration of a Set-Cookie attribute name.
Attribute names include
SameSite
,secure
,http-only
,value
,expires
,Max-Age
,path
, anddomain
. For more information, refer to RFC 6265: Set-Cookie.Use the
now
dynamic binding to dynamically set the value of a cookie attribute that represents time. For example, set the value of the attributeexpires
to one day after the expression is evaluated, as follows:{ "type": "SetCookieUpdateFilter", "config": { "cookies": { ".*": { "expires": "${now.plusDays(1).rfc1123}", ...
- attribute-value: runtime expression<string, boolean, or integer>, required
-
The replacement value for the named attribute. The value must conform to the expected type for the attribute name:
-
secure
: runtime expression<boolean>. Required ifSameSite
isnone
-
http-only
: runtime expression<boolean>. -
Max-Age
: runtime expression<number>. -
SameSite
, and all other attribute names: runtime expression<string>.
For all values except
expires
, specify${previous}
to reuse the existing value for the attribute. The following example adds five seconds to theMax-Age
attribute:"Max-Age": "${integer(previous+5)}",
If the named the Set-Cookie header doesn’t contain the named attribute,
${previous}
returns null. -
Examples
The following example updates attributes of all existing Set-Cookie headers:
{
"name": "SetCookieUpdateFilter",
"condition": "${find(request.uri.path, '/home')}",
"baseURI": "http://app.example.com:8081",
"heap": [],
"handler": {
"type": "Chain",
"config": {
"filters": [{
"type": "SetCookieUpdateFilter",
"config": {
"cookies": {
".*": {
"SameSite": "LAX",
"domain": "ig.example.com",
"Max-Age": "${session.maxAge}",
"Secure": "${true}",
"expires": 155...833
}
}
}
}],
"handler": "ReverseProxyHandler"
}
}
}
SingleSignOnFilter
Tests for the presence and validity of an SSO token in the cookie header of a request:
-
If an SSO token is present, the filter calls AM to validate the SSO token. If the SSO token is valid, the request continues along the chain. The token value and additional information are stored in the
ssoToken
context. For information, refer to SsoTokenContext. -
If the SSO token is not present, or is empty or invalid, IG checks the
goto
query parameter for the presence of the redirection marker:-
If the redirection marker parameter is present (for example,
_ig=true
), IG fails the request because the cookie domain is incorrectly configured. -
If the redirection marker is not present, IG redirects the user agent to the AM login page or another provided login page. For information about enabling, disabling, and naming the redirection marker, refer to the
redirectionMarker
property on this page.
-
For more information about SSO, refer to Authentication.
To prevent issues with performance when accessing large resources, such as .jpg and .js files, consider using the SingleSignOnFilter with the following options:
|
When AM is using CTS-based sessions, it does not monitor idle time for client-side sessions, and so refresh requests are ignored. When the SingleSignOnFilter is used for authentication with AM, after a time AM can view the session as idle even though the user continues to interact with IG. The user session can eventually time out. (From AM 6.5.3.) When AM is using CTS-based sessions, use the
|
WebSocket notifications for sessions
When WebSocket notifications are set up for sessions, IG receives a
notification from AM when a user logs out of AM, or when the
AM session is modified, closed, or times out. IG then evicts
entries that are related to the event from the sessionCache
.
For information about setting up WebSocket notifications, using them to clear the session cache, and including them in the server logs, refer to WebSocket notifications.

Default value of AM 6: AmService cannot discover the AM version, and
version
is not configured.
-
-
redirectionMarker
: object, optional-
"redirectionMarker": { "enabled": configuration expression<boolean>, "name": configuration expression<string> }
enabled
: configuration expression<boolean>, optional-
When
true
, use a redirection marker to limit the number of authentication redirects.When there is no SSO session due to, for example, SSO cookie name misconfiguration, an authentication request fails and is redirected back to IG. The scenario can result in infinite authentication redirects.
Consider enabling the redirection marker during development, then disabling it to prevent it being captured in bookmarks.
Default:
true
name
: configuration expression<string>, optional-
The name of the redirection marker query parameter to use when
enabled
istrue
.Default:
_ig
"authenticationService"
: configuration expression<string>,optional-
The name of an AM authentication tree or authentication chain to use for authentication.
Use only authentication trees with ForgeRock Identity Cloud. Authentication modules and chains are not supported. Default: AM’s default authentication tree.
For more information about authentication trees and chains, refer to Authentication nodes and trees and Authentication modules and chains in AM’s Authentication and SSO guide.
"realm"
: configuration expression<string>, optional-
The AM realm where the user is authenticated.
Default: The realm declared for
amService
.
"defaultLogoutLandingPage"
: configuration expression<url>, optional-

This parameter is effective only when
logoutExpression
is specified.Default: None, processing continues.
"loginEndpoint"
: runtime expression<url>, optional-
The URL of a service instance for the following tasks:
-
Manage authentication and the location to which the request is redirected after authentication.
-
Process policy advices after an AM policy decision denies a request with supported advices. The PolicyEnforcementFilter redirects the request to this URL, with information about how to meet the conditions in the advices.
For examples of different advice types, and the conditions that cause AM to return advices, see AM’s Authorization guide. For information about supported advice types in IG, refer to PolicyEnforcementFilter.
Default: The value of
url
inamService
Authentication can be performed in the following ways:
-
Directly through AM, with optional authentication parameters in the query string, such as
service
,module
, andrealm
. For a list of authentication parameters that you can include in the query string, see Authenticating (browser) in AM’s Authentication and SSO guide.The value must include a redirect with a
goto
parameter.The following example uses AM as the authentication service, and includes the
service
authentication parameter:"loginEndpoint": "https://am.example.com/openam?service=TwoFactor&goto=${urlEncodeQueryParameterNameOrValue(contexts.router.originalUri)}"
-
Through the URL of another application, with optional authentication parameters in the query string, such as
service
,module
, andrealm
. The application must create a session with an AM instance to set an SSO token and return the request to the redirect location.The value can optionally include a redirect with a
goto
parameter or different parameter name.The following example uses an authentication service that is not AM, and includes a redirect parameter:
"loginEndpoint": "https://authservice.example.com/auth?redirect=${urlEncodeQueryParameterNameOrValue(contexts.router.originalUri)}"
When using this option, review the cookie domains to make sure cookies set by the authentication server are properly conveyed to the IG instance.
-
"logoutExpression"
: runtime expression<boolean>, optional-
A flag to indicate whether a request initiates logout processing before reaching the protected application.
-
false
: The request does not initiate logout processing:-
If a valid AM session is found, the request is forwarded to the protected application.
-
If a valid AM session is not found, the request triggers login.
-
-
true
: The request initiates logout processing:-
If a valid AM session is found, the session is revoked and the request is forwarded as follows:
-
If
defaultLogoutLandingPage
is defined, the request is forwarded to the specified logout page. -
If
defaultLogoutLandingPage
is not defined, the request is forwarded to the protected application without any other validation.
-
-
If a valid session is not found, the request is forwarded to the protected application without any other validation.
-
To prevent unwanted access to the protected application, use
logoutExpression
with extreme caution as follows:-
Define a
defaultLogoutLandingPage
. -
If you don’t define a
defaultLogoutLandingPage
, specifylogoutExpression
to resolve totrue
only for requests that target dedicated logout pages of the protected application.
Consider the following examples when a
defaultLogoutLandingPage
is not configured:-
This expression resolves to
true
only for requests with/app/logout
in their path:"logoutExpression": ${startsWith(request.uri.rawPath, '/app/logout')}
When a request matches the expression, the AM session is revoked and the request is forwarded to the
/app/logout
page. -
This expression resolves to
true
for all requests that containlogOff=true
in their query parameters:"logoutExpression": ${find(request.uri.query, 'logOff=true')}
When a request matches the expression, the AM session is revoked and the request is forwarded to the protected application without any other validation. In this example, an attacker can bypass IG’s security mechanisms by simply adding
?logOff=true
to a request.
Default:
${false}
-
"logoutEndpoint"
: pattern, optional-
The use of this property is deprecated; use logoutExpression
instead. For more information, refer to the Deprecated section of the Release Notes.A string denoting a regular expression pattern for a URL. When a request matches the pattern, IG performs the logout process and the AM authentication token for the end user is revoked.
If a defaultLogoutLandingPage is specified, the request is redirected to that page. Otherwise, the request continues to be processed.
Default: Logout is not managed by this filter.
SqlAttributesFilter
Executes a SQL query through a prepared statement and exposes its first result.
Parameters in the prepared statement are derived from expressions. The query
result is exposed in an object whose location is specified by the target
expression. If the query yields no result, then the resulting object is empty.
The execution of the query is performed lazily; it does not occur until the first attempt to access a value in the target. This defers the overhead of connection pool, network and database query processing until a value is first required. This also means that the parameters expressions is not evaluated until the object is first accessed.
Usage
{
"name": string,
"type": "SqlAttributesFilter",
"config": {
"dataSource": JdbcDataSource reference,
"preparedStatement": configuration expression<string>,
"parameters": [ runtime expression<string>, ... ],
"target": lvalue-expression
}
}
Properties
"dataSource"
: JdbcDataSource reference, required-
dataSource
as a JNDI lookup name is deprecated; usedataSource
as a JdbcDataSource configuration object instead. For more information, refer to the Deprecated section of the Release Notes.The JdbcDataSource to use for connections. Configure JdbcDataSource as described in JdbcDataSource.
"preparedStatement"
: configuration expression<string>, required-
The parameterized SQL query to execute, with
?
parameter placeholders. "parameters"
: array of runtime expressions<strings>, optional-
The parameters to evaluate and include in the execution of the prepared statement.
See also Expressions.
"target"
: <lvalue-expression>, required-
Expression that yields the target object that will contain the query results.
See also Expressions.
Example
Using the user’s session ID from a cookie, query the database to find the user logged in and set the profile attributes in the attributes context:
{
"name": "SqlAttributesFilter",
"type": "SqlAttributesFilter",
"config": {
"target": "${attributes.sql}",
"dataSource": "java:comp/env/jdbc/mysql",
"preparedStatement": "SELECT f.value AS 'first', l.value AS 'last', u.mail AS 'email', GROUP_CONCAT(CAST(r.rid AS CHAR)) AS 'roles' FROM sessions s INNER JOIN users u ON ( u.uid = s.uid AND u.status = 1 ) LEFT OUTER JOIN profile_values f ON ( f.uid = u.uid AND f.fid = 1 ) LEFT OUTER JOIN profile_values l ON ( l.uid = u.uid AND l.fid = 2 ) LEFT OUTER JOIN users_roles r ON ( r.uid = u.uid ) WHERE (s.sid = ? AND s.uid <> 0) GROUP BY s.sid;",
"parameters": [ "${request.cookies[keyMatch(request.cookies,'JSESSION1234')][0].value}" ]
}
}
Lines are folded for readability in this example. In your JSON, keep the values
for "preparedStatement"
and "parameters"
on one line.
StaticRequestFilter
Creates a new request, replacing any existing request. The request can include
an entity specified in the entity
parameter. Alternatively, the request can
include a form, specified in the form
parameter, which is included in an
entity encoded in application/x-www-form-urlencoded
format if request method
is POST
, or otherwise as (additional) query parameters in the URI. The
form
and entity
parameters cannot be used together when the method
is set
to POST
.
Usage
{
"name": string,
"type": "StaticRequestFilter",
"config": {
"method": configuration expression<string>,
"uri": runtime expression<url>,

},
"entity": runtime expression<string>
}
}
Properties
"method"
: configuration expression<string>, required-
The HTTP method to be performed on the resource; for example,
GET
. "uri"
: runtime expression<url>, required-
The fully-qualified URI of the resource being accessed; for example,
http://www.example.com/resource.txt
.The result of the expression must be a string that represents a valid URI, but is not a real
java.net.URI
object. For example, it would be incorrect to use${request.uri}
, which is not a string but a mutable URI. "version"
: configuration expression<string>, optional-
Protocol version.
Default:
"HTTP/1.1"
"headers"
: map, optional-
One or more headers to set for a request, with the format
name: [ value, … ]
, where:In the following example, the header name is the value of the system variable defined in
cookieHeaderName
. The header value is stored incontexts.ssoToken.value
:"headers": { "${application['header1Name']}": [ "${application['header1Value'}" ] }
Default: Empty
"form"
: map, optional-
A form to include in the request and/or
application/x-www-form-urlencoded
entity, as name-value pairs, where:When a Request
method
isPOST
,form
is mutually exclusive withentity
.Examples:
-
In the following example, the field parameter names and values are hardcoded in the form:
"form": { "username": [ "demo" ], "password": [ "password" ] }
-
In the following example, the values take the first value of
username
andpassword
provided in the session:"form": { "username": [ "${session.username[0]}" ], "password": [ "${session.password[0]}" ] }
-
In the following example, the name of the first field parameter takes the value of the expression
${application['formName']}
when it is evaluated at startup. The values take the first value ofusername
andpassword
provided in the session:"form": { "${application['formName']}": [ "${session.username[0]}" ], "${application['formPassword']}": [ "${session.password[0]}" ] }
Default: Empty
-
"entity"
: runtime expression<string>, optional-
The message entity body to include in a request.
When a Request
method
isPOST
,entity
is mutually exclusive withform
.Methods are provided for accessing the entity as byte, string, or JSON content. For information, refer to Entity.
Attackers during reconnaissance can use messages to identify information about a deployment. For security, limit the amount of information in messages, and avoid using words that help identify IG. Default: Empty
Example
In the following example, IG replaces the browser’s original HTTP GET request with an HTTP POST login request containing credentials to authenticate to the sample application. For information about how to set up and test this example, refer to the Getting started.

SwitchFilter
Verifies that a specified condition is met. If the condition is met or no condition is specified, the request is diverted to the associated handler, with no further processing by the switch filter.
Usage
{
"name": string,
"type": "SwitchFilter",
"config": {
"onRequest": [
{
"condition": runtime expression<boolean>,
"handler": Handler reference
},
...
],
"onResponse": [
{
"condition": runtime expression<boolean>,
"handler": Handler reference
},
...
]
}
}
Properties
"onRequest"
: array of objects, optional-
Conditions to test (and handler to dispatch to, if
true
) before the request is handled. "onResponse"
: array of objects, optional-
Conditions to test (and handler to dispatch to, if
true
) after the response is handled. "condition"
: runtime expression<boolean>, optional-
A flag to indicate that a condition is met:
-
true
: The request is dispatched to the handler. -
false
: The request is not dispatched to the handler, and the next condition in the list is tried.When the last condition in the list returns
false
, the request is passed to the next filter or handler in the chain.
Default:
${true}
-
"handler"
: Handler reference, required-
Dispatch to this handler if the condition yields
true
.Provide either the name of a Handler object defined in the heap, or an inline Handler configuration object.
See also Handlers.
Example
This example intercepts the response if it is equal to 200 and executes the LoginRequestHandler. This filter might be used in a login flow where the request for the login page must go through to the target, but the response should be intercepted in order to send the login form to the application. This is typical for scenarios where there is a hidden value or cookie returned in the login page, which must be sent in the login form:
{
"name": "SwitchFilter",
"type": "SwitchFilter",
"config": {
"onResponse": [
{
"condition": "${response.status.code == 200}",
"handler": "LoginRequestHandler"
}
]
}
}
ThrottlingFilter
Limits the rate that requests pass through a filter. The maximum number of requests that a client is allowed to make in a defined time is called the throttling rate.
When the throttling rate is reached, IG issues an HTTP status code
429 Too Many Requests
and a Retry-After
header, whose value is rounded up
to the number of seconds to wait before trying the request again.
GET http://ig.example.com:8080/home/throttle-scriptable HTTP/1.1
. . .
HTTP/1.1 429 Too Many Requests
Retry-After: 10
Usage

: configuration expression<integer>, required-
The number of requests allowed through the filter in the time specified by
"duration"
.
"duration"
: configuration expression<duration>, required-
A time interval during which the number of requests passing through the filter is counted.

Examples
The following route defines a throttling rate of 6 requests/10 seconds to requests. For information about how to set up and test this example, refer to Configure Simple Throttling.
{
"name": "00-throttle-simple",
"baseURI": "http://app.example.com:8081",

}
TokenTransformationFilter
Transforms a token issued by AM to another token type.
The TokenTransformationFilter makes the result of the token transformation
available to downstream handlers in the sts
context. For information, refer to
StsContext.
The current implementation uses REST Security Token Service (STS) APIs to
transform an OpenID Connect ID Token (id_token
) into a SAML 2.0 assertion.
The subject confirmation method is Bearer, as described in
Profiles for the OASIS Security Assertion Markup Language (SAML) V2.0
.
The TokenTransformationFilter makes the result of the token transformation
available to downstream handlers in the issuedToken
property of the
${contexts.sts}
context.
The TokenTransformationFilter configuration references a REST STS instance that must be set up in AM before the TokenTransformationFilter can be used. The REST STS instance exposes a preconfigured transformation under a specific REST endpoint. For information about setting up a REST STS instance, see the AM documentation.
Errors that occur during the token transformation cause a error response to be returned to the client and an error message to be logged for the IG administrator.
Usage
{
"name": "string",
"type": "TokenTransformationFilter",
"config": {
"amService": AmService reference,
"idToken": runtime expression<string>,
"instance": configuration expression<string>,
"username": configuration expression<string>, //deprecated
"password": configuration expression<string> //deprecated
}
}
Properties
"amService"
: AmService reference, required-
The AmService heap object to use for the following properties:
-
agent
, the credentials of the IG agent in AM, to authenticate IG as an AM REST STS client, and to communicate WebSocket notifications from AM to IG. This credentials are evaluated when the route is initialized -
url
, the URL of an AM service to use for session token validation and authentication. Authentication and REST STS requests are made to this service. -
realm
, the AM realm containing the following information:-
The AM application that can make the REST STS request and whose credentials are the username and password.
-
The STS instance described by the instance field.
-
-
ssoTokenHeader
, the name of the HTTP header that provides the SSO token for the REST STS client subject. -
amHandler
, the handler to use for authentication and STS requests to AM.
-
"idToken"
: runtime expression<string>, required-
The value of the OpenID Connect ID token. The expected value is a string that is the JWT encoded
id_token
. "instance"
: configuration expression<string>, required-
An expression evaluating to the name of the REST STS instance.
This expression is evaluated when the route is initialized, so the expression cannot refer to
request
orcontexts
. "username"
: string, required-
The use of this property is deprecated; use the AmService property agent
instead. For more information, refer to the Deprecated section of the Release Notes.The username to authenticate IG as an AM REST STS client.
"password"
: expression, required-
The use of this property is deprecated; use the AmService property agent
instead. For more information, refer to the Deprecated section of the Release Notes.The password to authenticate IG as an AM REST STS client.
Example
The following example shows a configuration for a TokenTransformationFilter:
{
"type": "TokenTransformationFilter",
"config": {
"amService": "MyAmService",
"idToken": "${attributes.openid.id_token}",
"instance": "openig"
}
}
For an example of how to set up and test the TokenTransformationFilter, refer to Transform OpenID Connect ID tokens into SAML assertions.
TransactionIdOutboundFilter
Inserts the ID of a transaction into the header of a request.
The default TransactionIdOutboundFilter is created by IG, and used in ForgeRockClientHandler, as follows:
{
"name": "ForgeRockClientHandler",
"type": "ForgeRockClientHandler",
"config": {
"filters": [ "TransactionIdOutboundFilter" ],
"handler": "ClientHandler"
}
}
UmaFilter
This filter acts as a policy enforcement point, protecting access as a User-Managed Access (UMA) resource server. Specifically, this filter ensures that a request for protected resources includes a valid requesting party token with appropriate scopes before allowing the response to flow back to the requesting party.
Usage
{
"name": string,
"type": "UmaFilter",
"config": {
"protectionApiHandler": Handler reference,
"umaService": UmaService reference,
"realm": configuration expression<string>
}
}
Properties
"protectionApiHandler"
: Handler reference, required-
The handler to use when interacting with the UMA authorization server for token introspection and permission requests, such as a ClientHandler capable of making an HTTPS connection to the server.
For information, refer to Handlers.
"umaService"
: UmaService reference, required-
The UmaService to use when protecting resources.
For information, refer to UmaService.
"realm"
: configuration expression<string>, optional-
The UMA realm set in the response to a request for a protected resource that does not include a requesting party token enabling access to the resource.
Default:
uma
UriPathRewriteFilter
Rewrite a URL path, using a bidirectional mapping:
-
In the request flow,
fromPath
is mapped totoPath
. -
In the response flow,
toPath
is mapped tofromPath
.
IG overwrites a response header only when all of the following conditions are true:
-
The response includes a header such as
Location
orContent-Location
-
The URI of the response header matches the mapping
-
The value of response header is a relative path or its
scheme://host:port
value matches the base URI.
Usage
{
"name": string,
"type": "UriPathRewriteFilter",
"config": {
"mappings": object,
"failureHandler": Handler reference
}
}
Properties
"mappings"
: object, required-
One or more bidirectional mappings between URL paths. For example mappings, request scenarios, and an example route, refer to Examples.
{ "mappings": { "/fromPath1": "/toPath1", "/fromPath2": "/toPath2", ... } }
Paths are given by a
configuration expression<string>
. Consider the following points when you define paths:-
The incoming URL must start with the mapping path.
-
When more than one mapping applies to a URL, the most specific mapping is used.
-
Duplicate
fromPath
values are removed without warning. -
Trailing slashes
/
are removed from path values. -
If the response includes a
Location
orContent-Location
header with atoPath
in its URL, the response is rewritten withfromPath
.
-
"failureHandler"
: handler reference, optional-
Failure handler to be invoked if an invalid URL is produced when the request path is mapped, or when the response
Location
orContent-Location
header URI path is reverse-mapped.Provide an inline handler declaration, or the name of a handler object defined in the heap. See also Handlers.
Default: HTTP 500

Example route
The example route changes a request URL as follows:
-
The
baseURI
overrides the scheme, host, and port of a request URL. -
The UriPathRewriteFilter remaps the path of a request URL.
Requests to
http://ig.example.com:8080/mylogin
are mapped tohttp://app.example.com:8081/login
.Requests to
http://ig.example.com:8080/welcome
are mapped tohttp://app.example.com:8081/home
.Requests to
http://ig.example.com:8080/other
are mapped tohttp://app.example.com:8081/not-found
, and result in an HTTP 404.Requests to
http://ig.example.com:8080/badurl
are mapped to the invalid URLhttp://app.example.com:8081[
, and invoke the failure handler.
