When ACCESS::disable command is used in an iRule along with a Category Lookup agent in a per-request policy, the HTTP request we be incorrectly dropped and the connection reset. This error condition may also occur with other per-request policy agents.


The HTTP request will be dropped or the HTTP connection will stall and timeout.


APM deployed with a Per-Request policy using a Category-Lookup agent and an iRule which issues the ACCESS::disable command associated on the same virtual server.



Fix Information

When ACCESS::disable is used in an iRule on a virtual server with an Access Profile and Per-Request Policy assigned, BIG-IP APM will not run the Per-Request policy.
