What is CGI?
CGI Stands for Common Gateway Interface.
CGI programs are the most common way for Web servers to interact dynamically with users. Many HTML pages that contain forms, for example, use a CGI program to process the form's data once it's submitted. Another increasingly common way to provide dynamic feedback for Web users is to include scripts or programs that run on the user's machine rather than the Web server. These programs can be Java applets, Java scripts, or ActiveX controls. These technologies are known collectively as client-side solutions, while the use of CGI is a server-side solution because the processing occurs on the Web server.
What is CGI Used For?
In short, CGI defines how web servers and web browsers handle information from HTML forms on web pages. That's simplifying it, but you get the point. In the broader sense, however, the term 'CGI' is often used to mean "any program that runs on a web server and interacts with a web browser". You may hear someone ask, "Where can I get a CGI script to handle this form?" or "Use CGI to do what you need". What they are referring to is a program of some sort that runs on your web server.
History of CGI
CGI arose out of discussions between Rob McCool, John Franks, Ari Luotonen, George Phillips and Tony Sanders in 1993.
