The problem isn't the "creation" of the session, it is the simultaneous access of the session data without synchronization. When a browser a frame set, it will request all the frame at once. If the frames do any sort of processing on the session information, as is the case with squirrelmail, the last session to exit will overwrite all the changes made by prior frames. This can corrupt session information or lose versions of information. It is a HUGE problem that I don't see ANYONE addressing. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
