Greetings, fellow monks.

Let's say I have a script that's accessed by the following URL:

http://www.foo.com/cgi-bin/foo.pl?user=foolish&id=2

My main concern is that any user can simply change let's say "user=foolish" to "user=smartone" and just hit the enter key and the script will accept this user as if he is someone else.

I could solve this by making HTTP_REFERER checks, but since some scripts on the system can be accessed from multiple pages, it would be a royal pain in the a**...

Is there anyway to prevent the script from reloading itself without some form input?

Thanks in advance, my friends.
