Chapter 11. Conclusion

CGI Scripting for Programmers: Introduction

The Common Gateway Interface (CGI) underlies much of the modern web. It pro-

vides the most popular way by which web servers can respond to browser re-

quests by invoking programs and using the resulting output as their response.

CGI programs can make decisions based on information contained in browser

requests, and so can be used for vaious tasks, including dynamic page genera-

tion, processing ﬁll-in forms, interfacing to databases, implimenting ’shopping

carts’, etc.

This two-afternoon course covers the CGI itself, various aspects of HTML and

HTTP that are directly relevant to CGI programmers, and general CGI program-

ming issues including security. CGI programs can be written in a variety of lan-

guages, and their use is supported by most web servers. This course uses the

Perl scripting language to develop examples for use with an Apache web server

running under Linux. However the vast majority of the material covered is ap-

plicable to other languages and servers, and should be readily understandable

by anyone with programming experience. Some of the examples may be suitable

for general use.
