Questions tagged [cgi]

1) The Common Gateway Interface is a standard defining how web server software can delegate web page generation to a stand-alone application or executable file. 2) Computer Generated Imagery

This tag is mostly used for the Common Gateway Interface (CGI), which is a standard (see RFC 3875: CGI Version 1.1) that defines how web server software can delegate the generation of web pages to a stand-alone application, an executable file. Such applications are known as CGI scripts; they can be written in any programming language, although scripting languages are often used.

Less commonly on Stack Overflow, CGI may also be used to tag questions regarding Computer Generated Imagery.
