Have you taken a look at the HTML/JavaScript that's used on that site?

You can generate an unique key for each page and keep it in session, which can be validated with each request. This unique key will match only once for a page, if it does not match show the appropriate error message to the user. Also no-cache can be used for pages, so that browser does not cache them.
