note 59770 added to ref.session

I am facing an issue while working with Firefox. If I disable cookies and try to use session_register() it returns me a Session ID. Now if I call another php function, it returns me a new Session ID now. But in IE it returns me same Session ID. WHY??? Please help me. ---- Manual Page -- http://www.php.net/manual/en/ref.session.php Edit -- http://master.php.net/manage/user-notes.php?action=edit+59770 Delete: added to the manual -- http://master.php.net/manage/user-notes.php?action=delete+59770&report=yes&reason=added+to+the+manual Delete: bad code -- http://master.php.net/manage/user-notes.php?action=delete+59770&report=yes&reason=bad+code Delete: spam -- http://master.php.net/manage/user-notes.php?action=delete+59770&report=yes&reason=spam Delete: useless -- http://master.php.net/manage/user-notes.php?action=delete+59770&report=yes&reason=useless Delete: non-english -- http://master.php.net/manage/user-notes.php?action=delete+59770&report=yes&reason=non-english Delete: already in docs -- http://master.php.net/manage/user-notes.php?action=delete+59770&report=yes&reason=already+in+docs Delete: other reasons -- http://master.php.net/manage/user-notes.php?action=delete+59770&report=yes Reject -- http://master.php.net/manage/user-notes.php?action=reject+59770&report=yes Search -- http://master.php.net/manage/user-notes.php
