Just a thought, but as the session ID normally gets automatically added to the header request by a browser, could you not add it into the form itself as you move from one domain to another? Afaik, PHP tends to prefer the PHPSESSID as an element in the $_COOKIE array (or the $_REQUEST array which is made up from the cookie as well) so you might be able to do some clever playing around to achieve the effect? -- Thanks, Ash http://www.ashleysheridan.co.uk -- PHP General Mailing List (http://www.php.net/) To unsubscribe, visit: http://www.php.net/unsub.php
