Severity: 2-Critical

Symptoms

An iRule that calls HTTP::respond or HTTP::redirect in a non-HTTP iRule event can cause the TMM to core on the next pipelined request.

Impact

TMM core.

Conditions

HTTP::respond or HTTP::redirect used in a non-HTTP iRule event. A pipelined request follows the request that triggers the iRule response.

Workaround

Add the close header to the HTTP::response, and the connection will be automatically closed.

Fix Information

The TMM will no longer core due to not being able to handle the next pipelined request after a HTTP::respond or HTTP::redirect is used in a non-HTTP iRule event.
