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.
