Accessing web page in sequence

niju

Hi there,
I have three web pages (A,B,C). I need to prevent users accessing page
B and C without accessing A. What would be the best way to achieve this
rule?
Many Thanks

Depending on how critical accessing A before B and C is,
you could always check the server variable HTTP_REFERER
on all three pages and make sure it equals what you expected.

HTTP_REFERER can be spoofed if someone wanted to
go to the lengths of writing their own scripted browser sessions.

So, as long as you don't care/don't think someone would
bother with that, then I suspect this will do.

You could also utilize cookies to track which pages
they've been on and act accordingly.

The more robust way would be to store state info in the database that knows
where the user is in these 3 steps. If they go to a step beyond where they
should be, redirect them back to where they should.

If it is a simple scenario with only three web pages involved , the
easiest would be to set a Session Variable from page A and check it in B &
C.. Session("Visite dPageA") = "TRUE" or some thing..
