Answer 1

As a web application, you'll never have full control of the user's browser. Even if there was a way to instruct the browser to not store the page in history, which I doubt, you can't be sure it'll work. For example, a clever user could tweak an open-source browser to store every page in history, no matter what.

I think you should try to approach the problem from another angle. You could, for example, detect that it's the same form which is being forwarded and not send it to paypal the second time. The important thing is to do it server-side.
