CGI form
A CGI form is a way for an Internet user to interact dynamically with a Web server. An HTML page that contains a form may use a CGI program to process the form’s data once it has been submitted. For example: a user visits a Web page looking for specific information on a topic and finds that the Web page offers an e-mail newsletter service. In order for the user to receive the newsletter, he must fill out a CGI form with all of his applicable information. The form is then sent to the server using CGI, and the server processes the information that was sent in the form in order to add the user to its database and initiate the user’s newsletter service.
