You could just use a flag variable. If the page is submitted completly set the flag to true. If they use the back button with the flag set to true the form page could just redirect them, or give them a message.
Is there somewhere I could read about it?<BR>What flag variable?<BR>My form has a "Submit" button and if the user submits once - he can always click on "Back" and click my "Submit" button again.<BR>Maybe this has something to do with the caching of the page?<BR>Thanks...<BR>
