ASP authentication

Hi List, I am wondering what was the most secure way to allow users to access pages after authentication, i.e.: user authenticates in toto.asp, and after that, access is granted to tata_1.asp, tata_2.asp, ..., tata_n.asp. The trouble is obviously to ask the user once for his login / password (just in tot.asp), and to allow him to get to the other pages without asking each time his credentials. Googling around, I saw a couple of ways to meet my needs, but all seem to be weak: - I can set a hidden field where I can say "yes, he is authenticated" or "no, he is not", but anyone a little bit skilled can create a fake request having this set up by hand (with a proxy ! ), - I can check a session number or smth like that on each page...but this does not seem very reliable, - I can check IP adress...but when you use AOL for instance, IP adresses can change ! So none of the ways I found seem to be the best... Cheers list, for any reply / clue ! ------------------------------------------------------------------------------ Ethical Hacking at the InfoSec Institute.
