Impact

HTTP header modify agent cannot perform modification of headers/cookies.

Conditions

Receipt of HUDEVT_REQ_DONE before execution of HTTP Header Modify agent.

Workaround

None.

Fix Information

Appropriate check for disabling HTTP header agent only in serverside chain has been added and the check for the receipt of request has been processed has been removed.
