Instead of "pages", consider using a tabbed type of dialog. You do not have
to use actual links that look like tabs, maybe a 1-2-3 type of link. You
then store what the user has seen ( perhaps in session? persisted if you
need it to last longer) and allow him to go through any he has in his list.

If you want it to appear like separate pages, you can have three ASPX pages
inherit from the same base class and have the base class work the logic.

Another way to accomplish this is URL mapping. WIth MVC (still in beta,
although Go Live), you have complete control over this, as well, as the URL
is mapped to a controller which determines the view to show. You can set up
the URL to be something like:

http://mysite.com/secret/1
http://mysite.com/secret/2
http://mysite.com/secret/3
