Any suggestions or ideas. The only circumstance under which I can think this might happen is if the session id is not being propagated by cookie -- either because they're blocked in the browser, or because you have them switched off in php.ini. Even if you have session.use_trans_sid enabled, PHP cannot rewrite URLs in the header() call, so you have to include the session ID manually. You should do this regardless of whether you expect cookies to be enabled, so that it will work ok even in the unexpected situation of having cookies turned off. Fortunately, the standard PHP constant SID is provided for exactly this purpose, so your header call above should be: header("Location: $url?".SID); Finally, you should note that HTTP requires the Location: URL to be a full absolute one (i.e. starting http://) -- whilst it's true that all current mainstream browsers do the expected with a relative URL, it's better defensive programming to use only absolute URLs (just in case someone produces a browser that adheres to the standard!).
