Symptoms

In certain circumstances TMM might core when using an HTTP iRule command in a HTTP_REQUEST_SEND serverside event.

Impact

The command might either return invalid value or lead to a condition where TMM might core.

Conditions

- iRule with an HTTP command in a serverside event prior to the serverside being completely established, such as HTTP_REQUEST_SEND. - OneConnect configured on the virtual server.

Workaround

Use the {clientside} Tcl command to execute on the client side. Alternatively, you might use the HTTP_REQUEST_RELEASE event for HTTP inspection/modification on the server-side.

Fix Information

TMM no longer cores when using HTTP iRule commands on the server-side of the HTTP_REQUEST_SEND event.

Behavior Change
