Soln by Colin Angus Mackay - Each time a page is generated store in the Session object some unique value. If you press refresh or back the value will already exist in your Session object and you can throw the user out of the application. ---------- Venus Patel http://patelsinc.blogspot.com/ A student knows little about a lot.
