I have yet another concern.... I have designed a messaging sytem right....
WHen the user is in their inbox i don't wanna necessarily have the code u supplied at the top of the page because I want the users to be able to use the back button to come out of a message for example and return to the listing of messages (their inbox).
But then if they click the Delete button, it deletes the message and then reloads the page. I want the page they came from to expire!
How would I do that?
Also, is there a way to say delete/make all pages expire when the user signs out? So that despite how many times the back button is pressed they won't end back up in their inbox!
