 Introduction to PERL/CGI

Length: 2 Days

Tuition: $850


What past students had to say about this class:

 I felt I learned what I needed in order to effectively troubleshoot the many Perl scripts I come across in our various tools. In addition, I gained the knowledge to create my own scripts which would be of great use to me in my day-to-day operations. Thank you. ~V.P.\ Nokia

Overview
This two-day 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. To get the most from this course, you should have a thorough understanding of and experience with HTML 4.0. Experience with a programming language is not necessary, but will speed your progress.
