Whats the best way to stop users from using the back button.

[taco Bill]

What's the best way to stop users from backing up pages.

I want users to go through the site in 1 direction only ...

One web site I used when I tried to back up I got a "page has expired"
message that I liked quite a lot.

any tips ???

A method I can think of is to set the response.Expires = -1. The page will
exire the second it is sent, the back button will more or less be useless
for all the pages they access on your site.

Eg.
Start Page --> Page 1
Page 1 --> Page 2
Page 2 --> Page 3
Page 3 Back Page 2 (Page expired)
page 2 Back Page 1 (Page Expired)
Page 1 Back Start Page

That doesn't prevent users from refreshing the page though. If you want to
prevent users from going backwards at all, you need to keep track of where
users are in the sequence (e.g. SequencePage=1, SequencePage=2, etc.). You
can do that via cookies, or by setting a hidden form field value in each
page, or Session variables, or database tables. You keep a full list of the
pages on the server in an array. That way, when you receive a request, you
can check the user's current positional value. If the user is on page 2 and
requests page 1, for example, you simply do a server or client-side redirect
to the page you *want* them to see. In contrast, if the user is on page 2
and requests page 3, you allow the request to proceed normally. If the value
isn't present, you redirect to the beginning of the sequence.
