CGI: Common Gateway Interface
The Common Gateway Interface (CGI) is a standard for external gateway programs to interface with information servers such as HTTP servers. CGI scripts are commonly used on Web sites to achieve customised results. Generally, when the visitor performs some action, such as filling in a form or clicking on a link, the server executes a script using information input by the visitor. This allows the appearance or behaviour of the Web site to be customised for that visitor.
