I think this would be a good way. Let Javascript write an img tag that calls a PHP script which then inserts/sets a value in your session: document.write("<img src=\"setSessionVar.php\">"); So the script is only processed if JS is enabled. No need for a redirect and you should instantly have access to the session value.
