The Common Gateway Interface, or CGI, is a
standard for external gateway programs to interface with information
servers such as HTTP servers. A plain HTML document that the Web
daemon retrieves is static, which means it exists in a constant
state: a text file that doesn't change. A CGI program, on the other
hand, is executed in real-time, so that it
can output dynamic information. (From the CGI reference
