Detect that session in broken

[sudya]

Here is what I want to do - when the user uses the page the session is created. As soon as the user closes the page I want to catch that moment and perform last second things like committing data to DB, writing logs, etc. So how so I catch the fact that the user broke the session?

 

Thanks

I don't know that you can know when they close the page. If you're using sessions while logged in, you could run it when they log out.

That would be a bit creepy if you could know when ever a user left your site.

 

You can, however, log the last time a session was active such as when a user loads a page, and then use that information to expire sessions if the last action was >= X seconds ago.  Then you could do some logging with that stuff (I think that's how SMF knows how long you've been on the boards), but you could not, for example, get where a user went when leaving your site (unless you had dynamic links and they followed one).
