CGI (Computer Gateway Interface) is a means by which a server will acquire and process information from a web user and return a result. Form processing (in contrast to e-mail) is an example of CGI scripting. A web user fills out a form on a web page and submits it to the server. The CGI script located on the server processes it, forwards the requested information to the recipient of the submitted information and generally returns a success (or failure) result to the user who submitted the form.
