Use the Response.Expires object/property to expire the contents of pages 1,
2, and 3 immediately so that if the user "backs up" to these pages, they
will see "warning: the page contents have expired".
You can't prevent someone from going to these pages (well, you could
redirect them away from these pages if they aren't currently logged in, but
then you have to track the logged in status of a user).
