This said: PHP normally uses cookies to transfer the session ID to the client browser (controlled by the ini file setting "session.use_cookies"). If the client browser returns a session cookie there's no need for PHP to rewrite the URL links, thus SID is empty. If the client browser does NOT return a session cookie, SID contains the necessary information for URL rewriting. If you need to generate the SID value regardless of cookie/non-cookie settings, use $sid = session_name() . '=' . session_id(); All this can be found at http://www.php.net/manual/en/ref.session.php and the following pages. -- >O Ernest E. Vogelsinger (\) ICQ #13394035 ^ http://www.vogelsinger.at/
