How do I run code immediately before session end? 1

[tcstom]

I want to run some code immediately before a user session ends. I'm holding a user object in that session and when the session times out or is abandoned I want to pick up that user object and use it to clear out locks in the database before it is destroyed from the session. I've tried doing this in the global Session_End method but preliminary tests suggest that this is fired AFTER the session is ended. Is there any way to fire a similar method JUST BEFORE the session ends?

Web applications are stateless and they only respond to requests, so it's not a good idea to expect the server to do something without receiving a request. I'd rethink your approach with regards to why you need the locking, or look at another method for cleaning up the locks.

I would have thought the end of a session timeout could be considered as much of a request as the beginning of a session timeout. I had presumed some sort of event was fired to invoke the termination of a session so I was hoping I could handle it. Anyway, if can't be done perhaps I'll have to use the IP address to identify locks. It's running on an intranet so should be OK.

Why? Say for example, I start a session by navigating to my web page and therefore creating a request. Then, after one minute I close my browser, turn off my computer and walk away; the server has no way of knowing that I have done this. The session end event will still fire when the session times out (the default is 20 minutes) but I haven't made any request.

Yes, an event is fired (Session End) but it's just because the session has timed out. The session details no longer exist so you can't "clean up" after yourself.
