Right but hense you get into what I have said all along about sessions
I doubt we would ever rewrite all our url's to be session capable. That is why we strictly use cookies. Our Integrations work on two levels with most forums. One $checkpass is set to 1 if the session cookie equals a users session table entry or through identification from the userid cookie.
If you strictly go with sessions that is not a good thing so don't make the mistake of going down that road
True sessions are an old technology and everyone uses cookies nowadays as they do not want to login each time they go back to their sites.
Look forward to your demo. Now this is POSTNUKE right?
