Run something like this "response.write session.sessionid" on a blank asp page and match the session with the one keep passing around your page. If they are the same, then you can proceed to edit all the pages that use the sessionid in the querystring to call the session object instead.
Another note, that string you listed could be another session object. Maybe you can try session("oscsid") and see if it contains anything.
