Comment 7 for bug 316441

I think this needs to be looked into.

You cannot change the session.gc_maxlifetime in your php scripts using ini_set("session.gc_maxlifetime", SOMEVALUE);

Everything says it was read correctly but the garbage collector reads the session.gc_maxlifetime directly from the php.ini file and disregards the rest. You also cannot change the session path.

I have not done to much debugging but this is a very annoying issue when you want to change the session lifetime.
