I don't quite see why you want to prevent the user from resubmitting a form in the first place. Maybe you want to ensure that some operation is only carried out once during the session, but that is something different.

If the underlying problem really is that you carry out some operation, that should be carried out just once, use a server side transaction mechanism to ensure that two concurrent requests won't be able to carry out the operation at the same time, and some mechanism to skip the operation on subsequent requests.

By doing it this way, your web application will be more user friendly by not punishing the user for reloading the page.
