Using CGI to authenticate users is no less secure than using basic HTTP authentication, credentials are passed as plain text in both cases. You can allow your users to login via an SSL connection if you want it more secure.

Your best bet is to create a cookie that contains certain information (IP address, username, time, expiry, for example) and an MD5 digest of that information and send that back to the client after a successful login. Each subsequent request just makes sure the cookie hasn't been tampered with by checking the data in the cookie against the MD5 hash, you need not check the username against the password each time. This has the added benefit that you're not sending a username and password on each request. For a great explanation of all things authentication/authorization, have a look at the Eagle book chapter 6, it's mod_perl specific but explains the concepts very well.

    [perldigious]: but... but... perldigious is the unvirtuous kind of lazy in this case. :-)
    [perldigious]: Just kidding. Thanks 1nickt, I'll go ahead and do it the right way. An extra set of brackets and a little extra indentation isn't too much to ask.
    [karlgoethebier]: perldigious: perhaps a block if you are paranoid ;-)
    [choroba]: but undef %hash and %hash = () both work, too, but the first one keeps the memory allocated, while the latter makes it available for other parts of the program.
    [choroba]: iirc
    [perldigious]: karlgoethebier: Well it is a pretty old and complicated (for me) bit of code I wrote (poorly by my current standards), so I'm expecting everything to break when I add the scoping and find out what else is undesireably scope changed. :-)
    [perldigious]: Ah, thanks choroba, that sort of thing was precisely what I was wondering when I asked.
    [perldigious]: I didn't want to tie up memory unecessarily basically, I wanted to "delete" it specifically to free it up, and wasn't sure I was even accomplishing that.
