I can't just create a link on the last page back to the first page. Because if the user hits the back button on the browser they end up on page 2. Which can't happen. Once you are on the last page the user can't by anyway get back to page 2, unless they start over on page 1.
What I am planning on doing is passing the variables using the POST method. Then have a hidden variable pass with the pages. If this hidden variable is missing then redirect the user back to page 1. Thus if I can get page 2 to be cleared from the browsers cache after it has been displayed, if the user came back to this page using the back button the page will be reload from the server because it is not in cache, there for my code will not find the hidden variable and redirect the user back to page 1. I think the theory of this will work ok, but I don't know how to clear a page from the browsers cache after it is displayed. Thanks, Mark.
