CGI Script Input: Accepting Input To Perl Scripts

A CGI script will often require some form of input in order to operate.

In fact, only very trivial CGI scripts can be created without input.

We have introduced HTML Forms as a prime means of CGI input. However, there are several other forms of input to a CGI script.

In this section we will study:

• What form of input a CGI can receive
• How a CGI receives input.
• How to process the input in a CGI Perl script
• How a useful Perl library makes this (and other) tasks easy.
