Q:
I see the letters CGI on many web pages and in many URLs. What is CGI?

A:
CGI is short for Common Gateway Interface. Basically, a CGI script is a
program that runs on a web server. These scripts can do anything from counting hits on a web page to processing forms.

We use several types of these on our web site. In fact, when you signed up for this newsletter, you used a CGI script.
