logOut and disable browser back button

[chas28]

I would like to be able to log out a user and prevent the back button being used to reaccess the membership files.
I have tried using

FormsAuthentication.SignOut()
Session.Abandon()
and

Response.Expires = -1.

but users can still use the back button to enter the account.
How do I prevent this from happening?

Hi,
Maybe something in the logout actions that sets a session variable ( no Session.Abandon then) which a Page Load action on the previous page can check for?

Turkbear - The problem with that is when a web-browser's back-button is pressed, the web-browser retrieve the webpage from cache (not contacting the server), so a session wouldn't work in this case.
