Yesterday we learned how to send data to a
server from an HTML form.
We also know that the server will typically
pass that data in the form of environment variables to a CGI
script.
The CGI script will be responsible for
processing the form data and responding to the client in the form
of dynamically generated HTML.
But we still don't know what a CGI script
looks like.
So today we will look at CGI scripts
written in the programming language called Perl.
