After this header transmission the PHP script will actually continue to run, and its session data will be flushed to persistent storage only after the script eventually terminates. If this script is doing some lengthy operation it is quite possible that the client had already reacted to the redirect and fetched the relevant page, utilizing outdated session data. This will usually work without such problems: header('Location: somewhere-else.php?' . SID); exit; This might get you into trouble: header('Location: somewhere-else.php?' . SID); do_some_lengthy_operation(); // ... /* finally */ exit; so you might consider using session_write_close(); header('Location: somewhere-else.php?' . SID); do_some_lengthy_operation(); // ... /* finally */ exit; -- >O Ernest E. Vogelsinger (\) ICQ #13394035 ^ http://www.vogelsinger.at/
