When "ACCESS:session remove" can hang if it is used within the the ACCESS_POLICY_COMPLETED event. Other commands within the event may not execute.


ACCESS::session remove cannot be used in the ACCESS_POLICY_COMPLETED event, which may break some use cases. Some Access Exchange iRules are broken from this.


when ACCESS_POLICY_COMPLETED { ACCESS::session remove } This iRule was also observed to hang, with the client not receiving the 401 response: when ACCESS_POLICY_COMPLETED { ACCESS::respond 401 content "Error denied..." ACCESS:session remove }
