CGI with PERL

( Duration: 2 Days )

This CGI with PERL training course provides an in-depth understanding and hands-on knowledge of the capabilities of the de facto Internet client-server communications protocol: Common Gateway Interface (better known as CGI). In this course, you will learn about the specifications of the CGI protocol, details regarding its operation, and how to use the Perl programming language to perform common and powerful CGI communications and processing tasks on a Web server.

By attending CGI with PERL workshop, delegates will learn to:

Output dynamically generated HTML to a Web browser
Process data from an HTML form
Save data to a Web server

Understanding of, and experience with, HTML. Experience with a programming language is not necessary, but recommended.
