Modifying Authentication ASP Form

i have absolutely no experience using ASP or PHP, but I've been tasked with making a simple login page for certain clients. I found this tutorial which is almost what i'm looking for.

The one thing that i need to modify is each username, after login, must be directed to a specific protected page. Since the username and password get split into an array, i know there must be a way to also keep track of which pages are associated with which usernames, and then have that URL be evaluated in this line of code:

Code:
Response.Redirect ("/protected/default.asp")
if anyone has a better way of doing this simple form that would be very helpful as well, thanks
