We have requirement where we are asked to to trackdown the user session.

We are able to track down normal user login and log out. The challange we are facing is to track the time , where users don't hit a logout and just closes the window or keeps the window As-is and the session time out.

The requirement here is to capture the time when the session actually terminates(picked up by GC), and we also need to to highlight in the report that the concerned session is not logged out by the user but the system have actually terminated it.
