PHP session timeout is 0, but session still expiring
===

I am running Apache 2.2 with the latest build of PHP and mysql.

In my PHP.ini file, I can see the session timeout is set to 0, meaning the session stays live until the browser closes.

I have noticed however, that sometimes when coming in in the morning, and leaving the browser open and logged in overnight, the session seems to have expired.

Are there any other configuration settings that would be causing the session to expire? I just want to play around with the values and see what kind of time works best for my site.

Many thanks
