Hi JevgeniR,

APM does not utilize a specific response page for expired sessions. It just starts a new APM session and then redirects the user to /my.policy.

To stop those background JSON request from creating new APM sessions and also to respond those request with a 403 - Access Denied status code, you could attach the iRule below to your Virtual Server.

 

when ACCESS_SESSION_STARTED {
  if { [HTTP::header value "Accept"] starts_with "application/json" } { 
    ACCESS::session remove ACCESS::respond 401 "Access Denied" 
  } 
}

 

Cheers, Kai
