javascript logging users out?
 

i've got a web page that is automatically logging users out.

I've set the php.ini timeout longer than it logs me out. And, when i suspend my computer to RAM, the session stays open the next day when i unsuspend the computer.

Based on that, I'm thinking that javascript is actually doing the logging out (rather than a session timeout). How can i tell what javascript scripts have run in the last hour or so, so I can find if there is a javascript script logging my users out?

How could javascript kill a php session ? By deleting PHPSESSID cookie maybe ?
But in this case, php add the session id in $_GET, no ?
