APM Inactivity Timeout is not leading to session being closed. It stays open. Any reasons?

I see timeoutagent.php in F12, but session is not ending.

  • Hi,

     

    The timeoutagent page is called by a javascript inserted by APM. Its goal is to detect when your session reach the timeout to trigger another javascript displaying a dialog window explaining the session has expired or to trigger a redirect to the ending page

     

    it should not affect the timeout counters by itself

      whatever you mentioned is not happening actually. This is the issue. Actually due to this "timeoutgent.php" uri, session gets extended by 3 mins every time.

  • Hello Antish,

     

    Do you use an Irule on your service? if yes can you display it please. this could be caused a malfunction at the apm!!!

     

    Second point are you sure that your application does not send a regular request to check app availability (ajax call, ...)?
