CGI environment variables

When a browser makes a request to a server, the web server and the browser create environment variables. In ColdFusion, these variables are referred to as CGI environment variables. They take the CGI prefix regardless of whether the server uses a server API or CGI to communicate with the ColdFusion server.

Environment variables contain data about the transaction between the browser and the server, such as the IP Address, browser type, and authenticated username. You can reference CGI environment variables for a given page request anywhere in the page. CGI variables are read-only.

Note: The environment variables available to applications depend on the browser and server software.

Comments are no longer accepted for ColdFusion MX 6.1. ColdFusion 8 is the current version.

There should be a list of built-in cgi variables on this page.

This on-line documention in general is a joke, although a list of cgi variables can be found two pages to the right.

RTFM guys:
"The environment variables available to applications depend on the browser and server software"

So how can MM give you a definitive list of CGI variables?

Simply do this:
<cfump var="#CGI#">
