About CGI scripts

CGI (Common Gateway Interface) scripts are small programs used on many Web sites.

These programs are written in a computer language such as Perl, Tcl, C or C++, and they function between HTML pages and other programs on the Web server. For example, a CGI script could allow search data entered on a Web page to be sent to a database for lookup. It could also format the results of that search as an HTML page and send it back to the requester.

CGI scripts reside on your site, and they obtain data using environment variables that the Web server makes available to them.
