What is CGI script?
CGI (Common Gateway Interface) scripts are used to supplement basic HTML pages by making your Web site more interactive and functional. You can program many useful features in CGI scripts, such as hit counters, guest books, order forms and message boards. CGI is an alternative to Microsoft Active Server Pages (ASP). CGI programs are programs that actually execute on the web server, not on the client’s computer. They retrieve data that was sent from user input, manipulate it, and then return a message to the browser.
