IG 7.1.2


Limitations are inherent to the design, not bugs to be fixed:

Pre-exisiting fragment cookie overwrites the current fragment cookie during authentication

When a user has a pre-exisiting fragment cookie during authentication, for example, from a previous, incomplete authentication attempt, the pre-exisiting fragment overwrites the current fragment.

To minimize the impact of this limitation, the FragmentFilter cookie has a new property maxAge to configure the maximum duration for which it can remain valid.

Multiple spaces in unquoted cookie values are changed to a single space in JBoss

In JBoss, multiple spaces in unquoted cookie values are reduced to one space. For example:

testCookieName=cookie    value

is changed to

testCookieName=cookie value
No access to common time related functions in expressions

The value of System.currentTimeMillis() cannot currently be used in filters, such as JwtBuilderFilter, for claims such as exp and iat.

Scripts can access anything in their environment

IG scripts are not sandboxed, but instead have access to anything in their environment. You must make sure that the scripts that IG loads are safe.

Persist UMA shares

Shared resources cannot be persisted when IG restarts. They must be shared each time that IG restarts. For more information, see Support UMA Resource Servers.

Proxy WebSocket traffic when running in Jetty

When IG is running in the Jetty application container, it cannot proxy WebSocket traffic.

For more information, see Proxy WebSocket Traffic, and the websocket property of ClientHandler or ReverseProxyHandler.

Blocked ClientHandler with asynchronous HTTP clients

IG processes responses from asynchronous HTTP clients by using two thread pools of the same size:

  • The first thread pool receive the response headers.

  • The second thread pool completes the promise by to executing the callback and writing the response content to the stream. Reading and writing to the stream are synchronous, blocking operations.

Synchronous operation can cause routes to declare a blocked ClientHandler.

To recover from blocking, restart the route, or, if the route is config.json, restart the server. To prevent blocking, increase the number of worker threads.

Cannot use custom config.json in Studio

When a customized config.json is configured in Studio, Studio cannot deploy routes.

Log file of audit events can be overwritten

The log file of audit events can be overwritten when the log file is rotated.

When CsvAuditEventHandler is used to log audit events, the log file is overwritten if it is rotated before the file suffix, rotationFileSuffix, changes. By default, rotationFileSuffix is defined as a date in the format _yyyy-MM-dd.

Log files are rotated when one of the following limits is reached: maxFileSize, rotationInterval, or rotationTimes.

Set the log rotation parameters so that the log is not likely to rotate before rotationFileSuffix changes.

Cannot use SAML with AM policy agent

When SAML is used with an AM policy agent, class cast exceptions occur.

SAML fails with incorrect user-defined mapping

When the user defined mapping is incorrectly set, missing SAML assertions produce an infinite loop during authentication attempts.

For mutual authentication in HTTPS cannot specify which certificate to present

IG can check server certificates for HTTPS. However, for mutual authentication, the client certificate must be the first certificate in the KeyStore.
