Handlers

Handler objects process a request and context, and return a response. The way the response is created depends on the type of handler.

Chain

Dispatches a request and context to an ordered list of filters, and then finally to a handler.

Filters process the incoming request and context, pass it on to the next filter, and then to the handler. After the handler produces a response, the filters process the outgoing response and context as it makes its way to the client. Note that the same filter can process both the incoming request and the outgoing response but most filters do one or the other.

A Chain can be placed in a configuration anywhere that a handler can be placed.

Unlike ChainOfFilters, Chain finishes by dispatching the request to a handler. For more information, refer to ChainOfFilters.

Usage

{
     "name": string,
     "type": "Chain",
     "config": {
         "filters": [ Filter reference, ... ],
         "handler": Handler 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.
"handler": Handler reference, required: The Handler to which the Chain dispatches the request after it has traversed the specified filters.

Provide the name of a Handler object defined in the heap or an inline Handler configuration object.

Example

{
     "name": "LoginChain",
     "type": "Chain",
     "config": {
         "filters": [ "LoginFilter" ],
         "handler": "ReverseProxyHandler"
     }
}

ClientHandler

Sends requests to third-party services that are accessible through HTTP, and reconstructs the response from the received bytes. A third-party service is one that IG calls for data, such as an HTTP API or AM, or one to which IG submits data. When IG relays a request to a third-party service, IG is acting as a client of the service. IG is client-side.

Consider the following comparison of the ClientHandler and ReverseProxyHandler:

ClientHandler ReverseProxyHandler

	ClientHandler	ReverseProxyHandler
Use this handler to …	Send requests to third-party services accessed within a route. The service can be AM or an HTTP API. The service can be an HTTP endpoint, such as AM, IDM, Identity Cloud, or any custom HTTP API.	Send requests to the final service accessed by a route. The service can be the final downstream application.
If the service does not respond in time, this handler …	Propagates the error through the Promise flow. If the error is not handled within the route, for example, by a FailureHandler, the handler returns a `500 Internal Server Error` response.	Stops processing the request, and returns a `502 Bad Gateway` response.

Use this handler to …

Send requests to third-party services accessed within a route. The service can be AM or an HTTP API. The service can be an HTTP endpoint, such as AM, IDM, Identity Cloud, or any custom HTTP API.

Send requests to the final service accessed by a route. The service can be the final downstream application.

If the service does not respond in time, this handler …

Propagates the error through the Promise flow.

If the error is not handled within the route, for example, by a FailureHandler, the handler returns a 500 Internal Server Error response.

Stops processing the request, and returns a 502 Bad Gateway response.

When uploading or downloading large files, prevent timeout issues by increasing the value of soTimeout, and using a streaming mode, as follows:

Configure the streamingEnabled property of AdminHttpApplication.

Usage

{
  "name": string,
  "type": "ClientHandler",
  "config": {
    "vertx": object,
    "connections": configuration expression<number>,
    "waitQueueSize": configuration expression<number>,

  }
}

^* Legacy; no longer supported

Properties

"vertx": object, optional

Vert.x-specific configuration for the handler when IG is client-side. When IG is acting server-side, configure the connectors:vertx property of admin.json.

When IG sends requests to a proxied application or requests services from a third-party application, IG is client-side. IG is acting as a client of the application, and the application is acting as a server.

Vert.x options are described in HttpClientOptions.

The vertx object is read as a map, and values are evaluated as configuration expressions.

For properties where IG provides its own first-class configuration, Vert.x configuration options are disallowed, and the IG configuration option takes precedence over Vert.x options configured in vertx. The following Vert.x configuration options are disallowed client-side:

alpnVersions
connectTimeout
enabledCipherSuites
enabledSecureTransportProtocols
http2ClearTextUpgrade
idleTimeout
idleTimeoutUnit
keyCertOptions
keyStoreOptions
maxWaitQueueSize
pemKeyCertOptions
pemTrustOptions
pfxKeyCertOptions
pfxTrustOptions
port
protocolVersion
proxyOptions
ssl
trustOptions
trustStoreOptions
useAlpn
verifyHost

The following example configures the Vert.x configuration when IG is acting client-side. When IG is acting server-side, configure the connectors:vertx property of admin.json:

{
  "vertx": {
    "maxWebSocketFrameSize": 128000,
    "maxWebSocketMessageSize": 256000,
    "compressionLevel": 4,
    "maxHeaderSize": 16384
  }
}

The following example configures HTTP/2 connections when IG is acting client-side. The configuration allows IG to make HTTP/2 requests with large headers. When IG is acting server-side, configure the connectors:vertx property of admin.json:

{
  "vertx": {
    "initialSettings": {
      "maxHeaderListSize": 16384
    }
  }
}

"connections": configuration expression<number>, optional

The maximum number of concurrent HTTP connections in the client connection pool.

For information about the interaction between this property and waitQueueSize, see the description of waitQueueSize.

Default: 64

“waitQueueSize”: configuration expression<number>, optional

The maximum number of outbound requests allowed to queue when no downstream connections are available. Outbound requests received when the queue is full are rejected.

Use this property to limit memory use when there is a backlog of outbound requests, for example, when the protected application or third-party service is slow.

Configure waitQueueSize as follows:

Not set (default): The wait queue is calculated as the square of connections.
- If connections is not configured, then its default of 64 is used, giving the waitQueueSize of 4096.
- If the square of connections exceeds the maximum integer value for the Java JVM, the maximum integer value for the Java JVM is used.
-1: The wait queue is unlimited. Requests received when there are no available connections are queued without limit.
0: There is no wait queue. Requests received when there are no available connections are rejected.
A value that is less than the square of connections:

When the configuration is loaded, the configured value is used. IG generates a warning that the waitQueueSize is too small for the connections size, and recommends a different value.
A value where waitQueueSize plus connections exceeds the maximum integer value for the Java JVM:

When the configuration is loaded, the waitQueueSize is reduced to the maximum integer value for the Java JVM minus the value of connections. IG generates a warning.

Consider the following example configuration of connections and waitQueueSize:

{
  "handler" : {
    "name" : "proxy-handler",
    "type" : "ReverseProxyHandler",
    "MyCapture" : "all",
    "config": {
      "soTimeout": "10 seconds",
      "connectionTimeout": "10 seconds",
      "connections": 64,
      "waitQueueSize": 100
    }
  },
  "baseURI" : "http://app.example.com:8080",
  "condition" : "${find(request.uri.path, '/')}"
}

IG can propagate the request to the sample application using 64 connections. When the connections are consumed, up to 100 subsequent requests are queued until a connection is freed. Effectively IG can accommodate 164 requests, although user concurrency delay means more may be handled. Requests received when the waitQueue is full are rejected.

Default: Not set

"connectionTimeout": configuration expression<duration>, optional

Time to wait to establish a connection, expressed as a duration

Default: 10 seconds

"connectionTimeToLive": configuration expression<duration>, optional

Not supported

"disableReuseConnection": configuration expression<boolean>, optional

Not supported

"stateTrackingEnabled": configuration expression<boolean>, optional

Not supported

"numberOfWorkers": configuration expression<number>, optional

Not supported

"protocolVersion": configuration expression<enumeration>, optional

The version of HTTP protocol to use when processing requests:

HTTP/2:
- For HTTP, process requests using HTTP/1.1.
- For HTTPS, process requests using HTTP/2.
HTTP/1.1:
- For HTTP and HTTPS, process requests using HTTP/1.1.
Not set:
- For HTTP, process requests using HTTP/1.1.
- For HTTPS with alpn enabled in ClientTlsOptions, process requests using HTTP/1.1, with an HTTP/2 upgrade request. If the targeted server can use HTTP/2, the client uses HTTP/2.
  
  For HTTPS with alpn disabled in ClientTlsOptions, process requests using HTTP/1.1, without an HTTP/2 upgrade request.
  
  Note that alpn is enabled by default in ClientTlsOptions.

Default: Not set

In HTTP/1.1 request messages, a Host header is required to specify the host and port number of the requested resource. In HTTP/2 request messages, the Host header is not available.

In scripts or custom extensions that use HTTP/2, use UriRouterContext.originalUri.host or UriRouterContext.originalUri.port in requests.

"http2PriorKnowledge": configuration expression<boolean>, optional

A flag for whether the client should have prior knowledge that the server supports HTTP/2. This property is for cleartext (non-TLS requests) only, and is used only when protocolVersion is HTTP/2.

false: The client checks whether the server supports HTTP/2 by sending an HTTP/1.1 request to upgrade the connection to HTTP/2:
- If the server supports HTTP/2, the server upgrades the connection to HTTP/2, and subsequent requests are processed over HTTP/2.
- If the server does not support HTTP/2, the connection is not upgraded, and subsequent requests are processed over HTTP/1.
true: The client does not check that the server supports HTTP/2. The client sends HTTP/2 requests to the server, assuming that the server supports HTTP/2.

Default: false

"proxyOptions": ProxyOptions reference, optional

A proxy server to which requests can be submitted. Use this property to relay requests to other parts of the network. For example, use it to submit requests from an internal network to the internet.

Provide the name of a ProxyOptions object defined in the heap or an inline configuration.

Default: A heap object named ProxyOptions.

"soTimeout": configuration expression<duration>, optional

Socket timeout, after which stalled connections are destroyed, expressed as a duration.

If SocketTimeoutException errors occur in the logs when you try to upload or download large files, consider increasing soTimeout.

Default: 10 seconds

"temporaryStorage": TemporaryStorage reference, optional

The TemporaryStorage object to buffer the request and response, when the streamingEnabled property of admin.json is false.

Default: A heap object named TemporaryStorage.

tls: ClientTlsOptions reference, optional

Use of a TlsOptions reference is deprecated; use ClientTlsOptions instead. For more information, refer to the Deprecated section of the Release Notes.

Configure options for connections to TLS-protected endpoints, based on ClientTlsOptions. Define the object inline or in the heap.

Default: Connections to TLS-protected endpoints are not configured.

`"asyncBehavior": configuration expression<enumeration>, optional

Not supported

"retries": object, optional

Enable and configure retry for requests.

During the execution of a request to a remote server, if a runtime exception occurs, or a condition is met, IG waits for a delay, and then schedules a new execution of the request. IG tries until the allowed number of retries is reached or the execution succeeds.

A warning-level entry is logged if all retry attempts fail; a debug-level entry is logged if a retry succeeds.

"retries": {
  "enabled": configuration expression<boolean>,
  "condition": runtime expression<boolean>,
  "executor": ScheduledExecutorService reference,
  "count": configuration expression<number>,
  "delay": configuration expression<duration>,
  }
}

"enabled": configuration expression<boolean>, optional

Enable retries.

Default: true

"condition": runtine expression<boolean>, optional

An inline IG expression to define a condition based on the response, such as an error code.

The condition is evaluated as follows:

If true, IG retries the request until the value in count is reached.
If false, IG retries the request only if a runtime exception occurs, until the value in count is reached.

Default: ${false}

"executor": ScheduledExecutorService reference, optional

The ScheduledExecutorService to use for scheduling delayed execution of the request.

Default: ScheduledExecutorService

DesKeyGenHandler (deprecated)

This object is deprecated and not considered secure. For more information, refer to the Deprecated section of the Release Notes.

Consider using AM’s password replay post-authentication plugin class com.sun.identity.authentication.spi.JwtReplayPassword. The plugin encrypts the password captured by AM during authentication, and stores it in a session property. IG looks up the property, decrypts it, and replays the password. Authenticate with credentials from AM.

Generates a DES key for use with AM.

DispatchHandler

When a request is handled, the first condition in the list of conditions is evaluated. If the condition expression yields true, the request is dispatched to the associated handler with no further processing. Otherwise, the next condition in the list is evaluated.

Usage

{
  "name": string,
  "type": "DispatchHandler",
  "config": {
    "bindings": [
      {
        "condition": runtime expression<boolean>,
        "handler": Handler reference,
        "baseURI": runtime expression<url>,
      }, ...
    ]
  }
}

Properties

"bindings": array of objects, required

One or more condition and handler bindings.

"condition": runtime expression<boolean>, optional

A flag to indicate that a condition is met. The condition can be based on the request, context, or IG runtime environment, such as system properties or environment variables.

Conditions are defined using IG expressions, as described in Expressions, and are evaluated as follows:

true: The request is dispatched to the associated handler.
false: The next condition in the list is evaluated.

For examples, refer to Example conditions and requests.

Default: ${true}

"handler": Handler reference, required

The Handler to which IG dispaches the request if the associated condition yields true.

Provide the name of a Handler object defined in the heap or an inline Handler configuration object.

"baseURI": runtime expression<url>,optional

A base URI that overrides the existing request URI. Only scheme, host, and port are used in the supplied URI.

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.

In the following example, the binding condition looks up the hostname of the request. If it finds a match, the value is used for the baseURI. Otherwise, the default value is used:

{
  "properties": {
    "uris": {
      "app1.example.com": {
        "baseURI": "http://backend1:8080/"
      },
      "app2.example.com": {
        "baseURI": "http://backend2:8080/"
      },
      "default": {
        "baseURI": "http://backend3:8080/"
      }
    }
  },
  "handler": {
    "type": "DispatchHandler",
    "config": {
      "bindings": [
        {
          "condition": "${not empty uris[contexts.router.originalUri.host]}",
          "baseURI": "${uris[contexts.router.originalUri.host].baseURI}",
          "handler": "ReverseProxyHandler"
        },
        {
          "baseURI": "${uris['default'].baseURI}",
          "handler": "ReverseProxyHandler"
        }
      ]
    }
  }
}

Default: No change to the base URI

ForgeRockClientHandler

The ForgeRockClientHandler is a Handler available by default on the heap that chains a default ClientHandler with a TransactionIdOutboundFilter.

This Handler supports ForgeRock audit by supporting the initiation or propagation of audit information from IG to the audit framework. For more information, see AuditService.

The following default ForgeRockClientHandler is available as a default object on the heap, and can be referenced by the name ForgeRockClientHandler.

{
     "name": "ForgeRockClientHandler",
     "type": "Chain",
     "config": {

IdentityAssertionHandlerTechPreview

The IdentityAssertionHandlerTechPreview, ScriptableIdentityAssertionPluginTechPreview, and IdentityAssertionPluginTechPreview are available in Technology preview. They aren’t yet supported, may be functionally incomplete, and are subject to change without notice.

Use in an Identity Cloud authentication journey with a Gateway Communication node. For more information, refer to Identity Cloud’s Gateway Communication overview.

The IdentityAssertionHandlerTechPreview sets up an IdentityAssertionPluginTechPreview to manage local processing, such as authentication. The Handler then calls the plugin at runtime for each request.

An Identity Cloud authentication journey does the following:

Redirects users to IG for local authentication.
After local authentication, provides and identity assertion and redirects users back to the Identity Cloud authentication journey.

The Identity Cloud authentication journey provides:

A cryptographically-secure random value in a nonce to validate the identity assertion.
A returnUri to redirect the user back to Identity Cloud to continue the authentication journey.

Exceptions during local processing cause a redirect with an assertion JWT containing an assertionError claim. Exceptions that prevent the return of a valid assertion, such as an invalid incoming JWT or key error, cause an HTTP 500.

JwkSetHandler

Expose cryptographic keys as a JWK set. Use this handler to reuse exposed keys for their assigned purpose in a downstream application.

Consider the following limitations:

When the public key isn’t available, the corresponding private key can’t be exposed.

You are not recommended to expose private keys as a JWK.
Keys in secure storage, such as a Hardware Security Module (HSM) or remote server, can’t be exposed.

For a description of how secrets are managed, refer to About secrets.

For information about JWKs and JWK Sets, refer to JSON Web Key (JWK).

Usage

{
  "name": string,
  "type": "JwkSetHandler",
  "config": {
    "secretsProvider": SecretsProvider reference,
    "purposes": [ object, ... ],
    "exposePrivateSecrets": configuration expression<boolean>
  }
}

"secretsProvider": SecretsProvider reference, required: The SecretsProvider to use to resolve the secret. Provide either the name of a SecretsProvider object defined in the heap or specify a SecretsProvider object inline.
"purposes": array of objects, required: One or more purposes for the secret.

{
  "purposes": [
    {
      "secretId": configuration expression<secret-id>,
      "keyUsage": configuration expression<enumeration>
    },
    ...
  ]
}

"secretId": configuration expression<secret-id>, required

The secret ID of the key to be exposed in the JwkSet.

This secret ID must point to a CryptoKey.

"keyUsage": configuration expression<enumeration>, required

The allowed use of the key:

AGREE_KEY: Export the private key used in the key agreement protocol, for example, Diffie-Hellman.
ENCRYPT: Export the public key used to encrypt data.
DECRYPT: Export the private key used to decrypt data.
SIGN: Export the private key used to sign data.
VERIFY: Export the public key used to verify signature data.
WRAP_KEY: Export the public key used to encrypt (wrap) other keys.
UNWRAP_KEY: Export the private key used to decrypt (unwrap) other keys.

exposePrivateSecrets: configuration expression<boolean>, optional

A flag indicating whether to publish private keys in a JWK set. As a security safeguard, this property is false by default to prevent the accidental exposure of private keys.

true: Publish both public and private keys in the JWK set false: Publish only public keys in the JWK set

Default: false

Examples

This example uses a JwkSetHandler to expose a signing key used by the JwtBuilderFilter:

Set an environment variable for the base64-encoded secret to sign the JWT:
```
$ export SIGNING_KEY_SECRET_ID='cGFzc3dvcmQ='
```

Notice the following features of the route:

The route matches requests to /jwksethandler.
The JWT signing key is managed by the SysEnvStoreSecretStore in the heap, which refers to the SecretKeyPropertyFormat for the secret’s format.
The JwtBuilderFilter signature property refers to the JWT signing key in the SysEnvStoreSecretStore.
The JwkSetHandler refers to the JWT signing key.

Go to http://ig.example.com:8080/jwksethandler.

The signing key is displayed as an array, as follows:
```
{
  "keys": [
    {
      "k": "cGFzc3dvcmQ",
      "kid": "signing.key.secret.id",
      "kty": "oct",
      "use": "sig"
    }
  ]
}
```
The JWK set secret is ULR base64-encoded. Although the secret is set with the value cGFzc3dvcmQ=, the value cGFzc3dvcmQ is exposed.

ResourceHandler

Serves static content from a directory.

Usage

{
  "name": string,
  "type": "ResourceHandler",
  "config": {
    "directories": [ configuration expression<string>, ... ],
    "basePath": configuration expression<string>,
    "welcomePages": [ configuration expression<string>, ... ],
    "temporaryStorage": TemporaryStorage reference
  }
}

Properties

"directories": array of configuration expression<strings>, required: A list of one or more directories in which to search for static content.

When multiple directories are specified in an array, the directories are searched in the listed order.
"basePath": _configuration expression<string>, required if the route is not /: The base path of the incoming request for static content.

To specify no base path, leave this property out of the configuration, or specify it as "basePath": "" or "basePath": "/".

Default: "".
"welcomePages": array of configuration expression<strings>, optional: A set of static content to serve from one of the specified directories when no specific resource is requested.

When multiple sets of static content are specified in an array, the sets are searched for in the listed order. The first set that is found is used.

Default: Empty
"temporaryStorage": TemporaryStorage reference, optional: A TemporaryStorage object for the static content.

Default: TemporaryStorage heap object

Example

The following example serves requests to http://ig.example.com:8080 with the static file index.html from /path/to/static/pages/:

{
  "name": "StaticWebsite",
  "type": "ResourceHandler",
  "config": {
    "directories": ["/path/to/static/pages"],
    "welcomePages": ["index.html"]
  }
}

When the basePath is /website, the example serves requests to http://ig.example.com:8080/website:

{
  "name": "StaticWebsite",
  "type": "ResourceHandler",
  "config": {
    "directories": ["/path/to/static/pages"],
    "basePath": "/website",
    "welcomePages": ["index.html"]
  }
}

ReverseProxyHandler

Proxy requests to protected applications. When IG relays the request to the protected application, IG is acting as a client of the application. IG is client-side.

Consider the following comparison of the ClientHandler and ReverseProxyHandler:

ClientHandler ReverseProxyHandler

	ClientHandler	ReverseProxyHandler
Use this handler to …	Send requests to third-party services accessed within a route. The service can be AM or an HTTP API. The service can be an HTTP endpoint, such as AM, IDM, Identity Cloud, or any custom HTTP API.	Send requests to the final service accessed by a route. The service can be the final downstream application.
If the service does not respond in time, this handler …	Propagates the error through the Promise flow. If the error is not handled within the route, for example, by a FailureHandler, the handler returns a `500 Internal Server Error` response.	Stops processing the request, and returns a `502 Bad Gateway` response.

Use this handler to …

Send requests to third-party services accessed within a route. The service can be AM or an HTTP API. The service can be an HTTP endpoint, such as AM, IDM, Identity Cloud, or any custom HTTP API.

Send requests to the final service accessed by a route. The service can be the final downstream application.

If the service does not respond in time, this handler …

Propagates the error through the Promise flow.

If the error is not handled within the route, for example, by a FailureHandler, the handler returns a 500 Internal Server Error response.

Stops processing the request, and returns a 502 Bad Gateway response.

When uploading or downloading large files, prevent timeout issues by increasing the value of soTimeout, and using a streaming mode, as follows:

Configure the streamingEnabled property of AdminHttpApplication.

}

^* Legacy; no longer supported

Properties

"vertx": object, optional

Vert.x-specific configuration for the handler, where IG does not provide its own first-class configuration. Vert.x options are described in HttpClientOptions.

The vertx object is read as a map, and values are evaluated as configuration expressions.

alpnVersions
connectTimeout
enabledCipherSuites
enabledSecureTransportProtocols
http2ClearTextUpgrade
idleTimeout
idleTimeoutUnit
keyCertOptions
keyStoreOptions
maxWaitQueueSize
pemKeyCertOptions
pemTrustOptions
pfxKeyCertOptions
pfxTrustOptions
port
protocolVersion
proxyOptions
ssl
trustOptions
trustStoreOptions
useAlpn
verifyHost

The following example configures the Vert.x configuration when IG is acting client-side. When IG is acting server-side, configure the connectors:vertx property of admin.json:

{
  "vertx": {
    "maxWebSocketFrameSize": 128000,
    "maxWebSocketMessageSize": 256000,
    "compressionLevel": 4,
    "maxHeaderSize": 16384
  }
}

{
  "vertx": {
    "initialSettings": {
      "maxHeaderListSize": 16384
    }
  }
}

"connections": configuration expression<number>, optional

The maximum number of concurrent HTTP connections in the client connection pool.

For information about the interaction between this property and waitQueueSize, see the description of waitQueueSize.

Default: 64

“waitQueueSize”: configuration expression<number>, optional

The maximum number of outbound requests allowed to queue when no downstream connections are available. Outbound requests received when the queue is full are rejected.

Use this property to limit memory use when there is a backlog of outbound requests, for example, when the protected application or third-party service is slow.

Configure waitQueueSize as follows:

Not set (default): The wait queue is calculated as the square of connections.
- If connections is not configured, then its default of 64 is used, giving the waitQueueSize of 4096.
- If the square of connections exceeds the maximum integer value for the Java JVM, the maximum integer value for the Java JVM is used.
-1: The wait queue is unlimited. Requests received when there are no available connections are queued without limit.
0: There is no wait queue. Requests received when there are no available connections are rejected.
A value that is less than the square of connections:

When the configuration is loaded, the configured value is used. IG generates a warning that the waitQueueSize is too small for the connections size, and recommends a different value.
A value where waitQueueSize plus connections exceeds the maximum integer value for the Java JVM:

When the configuration is loaded, the waitQueueSize is reduced to the maximum integer value for the Java JVM minus the value of connections. IG generates a warning.

Consider the following example configuration of connections and waitQueueSize:

{
  "handler" : {
    "name" : "proxy-handler",
    "type" : "ReverseProxyHandler",
    "MyCapture" : "all",
    "config": {
      "soTimeout": "10 seconds",
      "connectionTimeout": "10 seconds",
      "connections": 64,
      "waitQueueSize": 100
    }
  },
  "baseURI" : "http://app.example.com:8080",
  "condition" : "${find(request.uri.path, '/')}"
}

Default: Not set

"connectionTimeout": configuration expression<duration>, optional

Time to wait to establish a connection, expressed as a duration

Default: 10 seconds

"connectionTimeToLive": configuration expression<duration>, optional

Not supported

"disableReuseConnection": configuration expression<boolean>, optional

Not supported

"stateTrackingEnabled": configuration expression<boolean>, optional

Not supported

"numberOfWorkers": configuration expression<number>, optional

Not supported

"protocolVersion": configuration expression<enumeration>, optional

The version of HTTP protocol to use when processing requests:

HTTP/2:
- For HTTP, process requests using HTTP/1.1.
- For HTTPS, process requests using HTTP/2.
HTTP/1.1:
- For HTTP and HTTPS, process requests using HTTP/1.1.
Not set:
- For HTTP, process requests using HTTP/1.1.
- For HTTPS with alpn enabled in ClientTlsOptions, process requests using HTTP/1.1, with an HTTP/2 upgrade request. If the targeted server can use HTTP/2, the client uses HTTP/2.
  
  For HTTPS with alpn disabled in ClientTlsOptions, process requests using HTTP/1.1, without an HTTP/2 upgrade request.
  
  Note that alpn is enabled by default in ClientTlsOptions.

Default: Not set

In HTTP/1.1 request messages, a Host header is required to specify the host and port number of the requested resource. In HTTP/2 request messages, the Host header is not available.

In scripts or custom extensions that use HTTP/2, use UriRouterContext.originalUri.host or UriRouterContext.originalUri.port in requests.

"http2PriorKnowledge": configuration expression<boolean>, optional

A flag for whether the client should have prior knowledge that the server supports HTTP/2. This property is for cleartext (non-TLS requests) only, and is used only when protocolVersion is HTTP/2.

false: The client checks whether the server supports HTTP/2 by sending an HTTP/1.1 request to upgrade the connection to HTTP/2:
- If the server supports HTTP/2, the server upgrades the connection to HTTP/2, and subsequent requests are processed over HTTP/2.
- If the server does not support HTTP/2, the connection is not upgraded, and subsequent requests are processed over HTTP/1.
true: The client does not check that the server supports HTTP/2. The client sends HTTP/2 requests to the server, assuming that the server supports HTTP/2.

Default: false

"proxyOptions": ProxyOptions reference, optional

A proxy server to which requests can be submitted. Use this property to relay requests to other parts of the network. For example, use it to submit requests from an internal network to the internet.

Provide the name of a ProxyOptions object defined in the heap or an inline configuration.

Default: A heap object named ProxyOptions.

"soTimeout": configuration expression<duration>, optional

Socket timeout, after which stalled connections are destroyed, expressed as a duration.

If SocketTimeoutException errors occur in the logs when you try to upload or download large files, consider increasing soTimeout.

Default: 10 seconds

"temporaryStorage": TemporaryStorage reference, optional

The TemporaryStorage object to buffer the request and response, when the streamingEnabled property of admin.json is false.

Default: A heap object named TemporaryStorage.

tls: ClientTlsOptions reference, optional

Use of a TlsOptions reference is deprecated; use ClientTlsOptions instead. For more information, refer to the Deprecated section of the Release Notes.

Configure options for connections to TLS-protected endpoints, based on ClientTlsOptions. Define the object inline or in the heap.

Default: Connections to TLS-protected endpoints are not configured.

`"asyncBehavior": configuration expression<enumeration>, optional

Not supported

"retries": object, optional

Enable and configure retry for requests.

A warning-level entry is logged if all retry attempts fail; a debug-level entry is logged if a retry succeeds.

"retries": {
  "enabled": configuration expression<boolean>,
  "condition": runtime expression<boolean>,
  "executor": ScheduledExecutorService reference,
  "count": configuration expression<number>,
  "delay": configuration expression<duration>,
  }
}

"enabled": configuration expression<boolean>, optional

Enable retries.

Default: true

"condition": runtine expression<boolean>, optional

An inline IG expression to define a condition based on the response, such as an error code.

The condition is evaluated as follows:

If true, IG retries the request until the value in count is reached.
If false, IG retries the request only if a runtime exception occurs, until the value in count is reached.

Default: ${false}

"executor": ScheduledExecutorService reference, optional

The ScheduledExecutorService to use for scheduling delayed execution of the request.

Default: ScheduledExecutorService

Route

Routes are JSON-encoded configuration files that you add to IG to manage requests. You can add routes in the following ways:

Manually into the filesystem.
Through Common REST commands. For information, refer to Routes and Common REST.
Through Studio. For information, refer to the Studio guide.

Routes handle requests and their context, and then hand off any request they accept to a Handler.

When a route has a condition, it handles only requests that meet the condition. When a route has no condition, it handles any request.

Routes inherit settings from their parent configuration. This means that you can configure global objects in the config.json heap, for example, and then reference the objects by name in any other IG configuration.

Usage

{
  "handler": Handler reference,
  "heap": [ object, ... ],
  "condition": runtime expression<boolean>,
  "name": string,
  "secrets": {
    "stores": [ SecretStore reference, ... ]
  }, //deprecated
  "session": AsyncSessionManager reference,
  "auditService": AuditService reference,
  "globalDecorators": map,
  "decorator name": Decorator object
}

^(*)Deprecated

Properties

"handler": Handler reference, required

The Handler to which IG dispaches requests.

Provide the name of a Handler object defined in the heap or an inline Handler configuration object.

"heap": array of objects, optional

Heap object configuration for objects local to this route.

Objects referenced but not defined here are inherited from the parent.

You can omit an empty array. If you only have one object in the heap, you can inline it as the handler value.

Route metrics at the Prometheus Scrape Endpoint

Route metrics at the Prometheus Scrape Endpoint have the following labels:

name: Route name, for example, My Route.

If the router was declared with a default handler, then its metrics are published through the route named default.
route: Route identifier, for example, my-route.
router: Fully qualified name of the router, for example, gateway.main-router.

The following table summarizes the recorded metrics:

Router

A Handler that performs the following tasks:

Defines the routes directory and loads routes into the configuration.
Depending on the scanning interval, periodically scans the routes directory and updates the IG configuration when routes are added, removed, or changed. The router updates the IG configuration without needing to restart IG or access the route.
Manages an internal list of routes, where routes are ordered lexicographically by route name. If a route is not named, then the route ID is used instead. For more information, refer to Route.
Routes requests to the first route in the internal list of routes, whose condition is satisfied.

Because the list of routes is ordered lexicographically by route name, name your routes with this in mind:
- If a request satisfies the condition of more than one route, it is routed to the first route in the list whose condition is met.
- Even if the request matches a later route in the list, it might never reach that route.
If a request does not satisfy the condition of any route, it is routed to the default handler if one is configured.

The router does not have to know about specific routes in advance - you can configure the router first and then add routes while IG is running.

Studio deploys and undeploys routes through a main router named _router, which is the name of the main router in the default configuration. If you use a custom config.json, make sure it contains a main router named _router.

Usage

{
    "name": string,
    "type": "Router",
    "config": {
        "defaultHandler": Handler reference,
        "directory": configuration expression<string>,
        "scanInterval": configuration expression<duration>
    }
}

An alternative value for type is RouterHandler.

Properties

"defaultHandler": Handler reference, optional

Handler to use when a request does not satisfy the condition of any route.

Provide either the name of a handler object defined in the heap or an inline handler configuration object.

Default: If no default route is set either here or in the route configurations, IG aborts the request with an internal error.

Router metrics at the Prometheus Scrape Endpoint

Router metrics at the Prometheus Scrape Endpoint have the following labels:

fully_qualified_name: Fully qualified name of the router, for example, gateway.main-router.
heap: Name of the heap in which this router is declared, for example, gateway.
name: Simple name declared in router configuration, for example, main-router.

The following table summarizes the recorded metrics:

Name Monitoring type Description

Name	Monitoring type	Description
`ig_router_deployed_routes`	`Gauge`	Number of routes deployed in the configuration.

ig_router_deployed_routes

Gauge

Number of routes deployed in the configuration.

For more information about the the Prometheus Scrape Endpoint, refer to Prometheus Scrape Endpoint.

Router metrics at the Common REST Monitoring Endpoint

Router metrics at the Common REST Monitoring Endpoint are JSON objects, with the following form:

[heap name].[router name].deployed-routes

The following table summarizes the recorded metrics:

Name Monitoring type Description

Name	Monitoring type	Description
`deployed-routes`	`Gauge`	Number of routes deployed in the configuration.

deployed-routes

Gauge

Number of routes deployed in the configuration.

For more information about the the Common REST Monitoring Endpoint, refer to Common REST Monitoring Endpoint.

Example

The following config.json file configures a Router:

{
  "handler": {
    "type": "Router",
    "name": "_router",
    "baseURI": "http://app.example.com:8081",
    "capture": "all"
  },
  "heap": [
    {
      "name": "JwtSession",
      "type": "JwtSession"
    },
    {
      "name": "capture",
      "type": "CaptureDecorator",
      "config": {
        "captureEntity": true,
        "_captureContext": true
      }
    }
  ]
}

All requests pass with the default settings to the Router. The Router scans $HOME/.openig/config/routes at startup, and rescans the directory every 10 seconds. If routes have been added, deleted, or changed, the router applies the changes.

The main router and any subrouters build the monitoring endpoints. For information about monitoring endpoints, refer to Monitoring endpoints.

More information

org.forgerock.openig.handler.router.RouterHandler

SamlFederationHandler (deprecated)

This handler is deprecated; use the SamlFederationFilter instead.

A handler to play the role of SAML 2.0 Service Provider (SP).

Consider the following requirements for SamlFederationHandler:

This handler does not support filtering; do not use it as the handler for a chain, which can include filters.
Do not use this handler when its use depends on something in the response. The response can be handled independently of IG, and can be null when control returns to IG. For example, do not use this handler in a SequenceHandler where the postcondition depends on the response.
Requests to the SamlFederationHandler must not be rebased, because the request URI must match the endpoint in the SAML metadata.

SAML in deployments with multiple instances of IG

IG uses the federation libraries from AM (also referred to as the Fedlet) to implement SAML. When IG acts as a SAML service provider, the session information is stored in the fedlet, not the session cookie. In deployments that use multiple instances of IG as a SAML service provider, it is therefore necessary to set up sticky sessions so that requests always hit the instance where the SAML interaction was started.

For information, refer to Session state considerations in AM’s SAML v2.0 guide.

For more information, refer to About session stickiness and session replication for Tomcat and About session stickiness and session replication for Jetty

Usage

{
    "name": string,
    "type": "SamlFederationHandler",
    "config": {
        "assertionMapping": map or configuration expression<map>,
        "redirectURI": configuration expression<url>,
        "secretsProvider": SecretsProvider reference,
        "assertionConsumerEndpoint": configuration expression<url>,
        "authnContext": configuration expression<string>,
        "authnContextDelimiter": configuration expression<string>,
        "logoutURI": configuration expression<url>,
        "sessionIndexMapping": configuration expression<string>,
        "singleLogoutEndpoint": configuration expression<url>,
        "singleLogoutEndpointSoap": configuration expression<url>,
        "SPinitiatedSLOEndpoint": configuration expression<url>,
        "SPinitiatedSSOEndpoint": configuration expression<url>,
        "useOriginalUri": configuration expression<boolean>,
        "subjectMapping": configuration expression<string>
    }
}

Properties

"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 and password are mapped to SAML assertion names mail and mailPassword :

{
  "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.

"redirectURI": configuration expression<url>, required

The page that the filter used to HTTP POST a login form recognizes as the login page for the protected application.

This is how IG and the Federation component work together to provide SSO. When IG detects the login page of the protected application, it redirects to the Federation component. Once the Federation handler validates the SAML exchanges with the IDP, and sets the required session attributes, it redirects back to the login page of the protected application. This allows the filter used to HTTP POST a login form to finish the job by creating a login form to post to the application based on the credentials retrieved from the session attributes.

"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.

Default: Empty.

"assertionConsumerEndpoint": configuration expression<string>, optional

Default: fedletapplication (same as the Fedlet)

If you modify this attribute, change the metadata to match.

"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 sets session.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: |

"logoutURI": configuration expression<string>, optional

Set this to the URI to visit after the user is logged out of the protected application.

You only need to set this if the application uses the single logout feature of the Identity Provider.

"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.

As an example, if you set "sessionIndexMapping": "mySessionIndex", then IG sets session.mySessionIndex to the session index specified in the assertion. This results in the session containing something like "mySessionIndex": "s24ccbbffe2bfd761c32d42e1b7a9f60ea618f9801".

Default: map to session.sessionIndex

"singleLogoutEndpoint": configuration expression<string>, optional

Default: fedletSLORedirect (same as the Fedlet)

If you modify this attribute, change the metadata to match.

"singleLogoutEndpointSoap": configuration expression<string>, optional

Default: fedletSloSoap (same as the Fedlet)

If you modify this attribute, change the metadata to match.

"SPinitiatedSLOEndpoint": configuration expression<string>, optional

Default: SPInitiatedSLO

If you modify this attribute, change the metadata to match.

"SPinitiatedSSOEndpoint": configuration expression<string>, optional

Default: SPInitiatedSSO

If you modify this attribute, change the metadata to match.

"useOriginalUri": configuration expression<boolean>, optional

When true, use the original URI instead of a rebased URI when validating RelayState and Assertion Consumer Location URLs. Use this property if a baseUri decorator is used in the route or in config.json.

Default: false

"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.

As an example, if you set "subjectMapping": "mySubjectName", then IG sets session.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": "vtOk+APj1s9Rr4yCka6V9pGUuzuL".

Default: map to session.subjectName

Example

For an example of how to set up IG as a SAML service provider, refer to SAML.

In the following example, IG receives a SAML 2.0 assertion from the IDP, and then logs the user in to the protected application using the username and password from the assertion:

{
    "name": "SamlFederationHandler",
    "type": "SamlFederationHandler",
    "config": {
        "assertionMapping": {
            "username": "mail",
            "password": "mailPassword"
        },
        "redirectURI": "/login",
        "logoutURI": "/logout"
    }
}

ScriptableHandler

Creates a response to a request by executing a script.

Scripts must return either a Promise<Response, NeverThrowsException> or a Response.

This section describes the usage of ScriptableHandler. For information about script properties, available global objects, and automatically imported classes, see Scripts.

Usage

{
    "name": string,
    "type": "ScriptableHandler",
    "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 ScriptableHandler, refer to Scripts.

SequenceHandler

Processes a request through a sequence of handlers and post conditions, as follows:

A request is treated by handler1, and then postcondition1 is evaluated.
If postcondition1 is true, the request is then treated by handler2, and so on.

{
  "handler": handler1,
  "postcondition": expression1
},
{
  "handler": handler2,
  "postcondition": expression2
},
...

Use this handler for multi-request processing, such as retrieving a form, extracting form content (for example, a nonce), and then submitting it in a subsequent request.

Usage

{
    "name": string,
    "type": "SequenceHandler",
    "config": {
        "bindings": [
            {
                "handler": Handler reference,
                "postcondition": runtime expression<boolean>
            }
        ]
    }
}

Properties

"bindings": array of objects, required

A list of handler and postcondition bindings.

"handler": Handler reference, required

The handler to dispatch the request to when it is the first handler in the bindings, or for subsequent handlers when their previous postcondition yields true.

Provide the name of a Handler object defined in the heap or an inline Handler configuration object.

"postcondition": runtime expression<boolean>, optional

A flag to indicate that a post condition is met:

true: The request is dispatched to the next handler in bindings.
false: The sequence stops.

Postconditions are defined using IG expressions, as described in Expressions.

Default: ${true}

StaticResponseHandler

Creates a response to a request statically, or based on something in the context.

Usage

{
  "name": string,
  "type": "StaticResponseHandler",
  "config": {
    "status": configuration expression<number>,
    "reason": configuration expression<string>,
    "headers": {
       configuration expression<string>: [ runtime expression<string>, ... ], ...
    },
    "trailers": {
       configuration expression<string>: [ runtime expression<string>, ... ], ...
    },
    "entity": runtime expression<string> or [ runtime expression<string>, ... ]
  }
}

Properties

"status": Status object

The response status. For more information, refer to Status.

"reason": configuration expression<string>, optional

Used only for custom HTTP status codes. For more information, refer to Response Status Codes and Status Code Registry.

"headers": map, optional

One or more headers to set for a response, with the format name: [ value, … ], where:

name is a configuration expression<string> for a header name. If multiple expressions resolve to the same final string, name has multiple values.
value one or more a runtime expression<strings> for header values.

When the property entity is used, set a Content-Type header with the correct content type value. The following example sets the content type of a message entity in the response:

"headers": {
  "Content-Type": [ "text/html; charset=UTF-8" ]
}

The following example is used in federate-handler.json to redirect the original URI from the request:

"headers": {
  "Location": [
     "http://sp.example.com:8080/saml/SPInitiatedSSO"
  ]
}

Default: Empty

"trailers": map, optional

One or more trailers to set for a response, with the format name: [ value, … ], where:

name is a configuration expression<string> for a trailer name. If multiple expressions resolve to the same string, name has multiple values.

The following trailer names are not allowed:
- Message framing headers (for example, Transfer-Encoding and Content-Length)
- Routing headers (for example, Host)
- Request modifiers (for example, controls and conditionals such as Cache-Control, Max-Forwards, and TE)
- Authentication headers (for example, Authorization and Set-Cookie)
- Content-Encoding
- Content-Type
- Content-Range
- Trailer
value is one or more runtime expression<strings> for trailer values.

Default: Empty

"entity": runtime expression<string> or array of runtime expression<string>, optional

The message entity body to include in a response.

If a Content-Type header is present, the entity must conform to the header and set the content length header automatically.

Methods are provided for accessing the entity as byte, string, or JSON content. For information, refer to Entity.

Attackers during reconnaissance can use response 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

{
  "name": "ErrorHandler",
  "type":"StaticResponseHandler",
  "config": {
    "status": 500,
    "headers": {
      "Content-Type": [ "text/html; charset=UTF-8" ]
    },
