note 57098 added to function.session-cache-expire

After recieving a "bogus" mark on a bug report i've tried to find out the differences between cache_expire and what was causing a session delete after 24 minutes. cache_expire is used for cached session pages and has nothing to do with the session data The garbage collector controls the session data and destroys sessions which are older then 1440 seconds (24 minutes) by default. So to keep a session alive longer then 24 minutes (for example when a visitor tries to POST a huge message that took him 1 hour to type), you must modify the session.gc_maxlifetime thru ini_set() Somehow i couldn't find anything in the PHP documentation regarding this and due to that me (and i think many others) got the wrong ideas regarding PHP sessions. A few examples to fix session timeout are already posted below but in my opinion they all missed session.gc_maxlifetime ---- Manual Page -- http://www.php.net/manual/en/function.session-cache-expire.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+57098 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+57098&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+57098&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+57098&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+57098&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+57098&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+57098&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+57098&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+57098&report=yes Search -- http://master.php.net/manage/user-notes.php
