I thought that might be your reasoning, but expiring the page will achieve
the exact oposite of that! Backing up to an expired page will make IE
either ask if you want to resubmit your data ("a box with yes and no,
ehrm, let's click yes!") or worse, impicitely do it for you.The best ways to prevent resubmitting is to see if it already has been done by having some special ID on the page and in the database, which you check against before inserting/updating/whatever and throw an error yourself, or after the submit, do a redirect to another page. Downside of that is that if the redirect doesn't load for whaterver reason, the user may use back and click submit on the form again. So maybe a combination of the two is the safest way to go!
