If the flow inside a HTTP_REQUEST event raised by the explicit proxy is expired, the TMM may crash.


If state-changing commands are used within the HTTP_REQUEST event raised by the explicit proxy, they may not work correctly, and TMM might crash.


The explicit proxy is configured for HTTP, and the HTTP_REQUEST iRule event is used.


Avoid the HTTP_REQUEST event if possible.

Fix Information

The TMM no longer crashes when under load when the HTTP_REQUEST iRule handler is used with the explicit proxy. HTTP state-changing commands used within HTTP_REQUEST on the explicit proxy works correctly.
