Yes, the url is valid..because if I comment out or remove the faulty code in
the JSP page, it works fine and no exception is thrown at all..the JSP
output is read in, and I apply XSL to it..all that works.
Cookies are used only for session id, nothing else. That is why I send the
jsessionid= with the session id value to the JSP page, so it ties it to the
same session that the current session the request that came in belongs to.
