[prog] CGI programming

[Dan Richter]

Hi everyone.

I haven't seen much traffic on this list in awhile, so maybe I'll stir 
things up a little.

I'm trying to learn CGI programming. I've written and run some extremely 
basic CGI scripts, but it's obvious that I'm going to need some outside 
help to get much further. Can anyone suggest a good introduction to CGI 
programming? Can anyone explain to me how CGI programming is usually done 
in Perl (what helper functions/classes are used)?

And here's a very specific question: I've noticed that Apache included the 
following variable:
    UNIQUE_ID=tPxaBwoAAFoAAHpvDoUAAAAD
To state the obvious, it's some sort of unique ID. It seems to change every 
time the script is invoked. How unique is it? Is it guaranteed to be unique 
for this machine for, say, a decade?
