Additional Resources
I've written some supplemental
scripts that will further illustrate the concepts covered
in this lesson and hopefully give you a head start on project
4.
I found many reasources for this lesson and had a hard time
picking just a few. If you want more or different explanations,
try these resources: Getting
Information into your Script, CGI
Made Easy Using Libraries, Server
Side Processing of Form Data. I wasn't completely satisfied
with the textbook's explanations, so it might be worth a glance.
One page to definitely bookmark is the CGI.pm
home page. Be sure to review how to prevent denial of
service attacks (remember those hackers that brought down
ebay in 1999?)
Before CGI.pm, most folks were using cgi-lib.pl
and many programmers still use it.
Again I direct your attention to one of the O'Reilly
books... specifically CGI
Programming with Perl (the updated edition of CGI Programming
on the WWW). Chapter 4 covers Forms and CGI and Chapter 5
covers CGI.pm. If you have the book or can find it at the
library, be sure to review the material there. I have found
this to be the most comprehensive book on CGI programming.
