 What are environment variables and how do they help me?

Environment variables are pieces of information gathered by the Common Gateway Interface (CGI). This data is available to all cgi programs, allowing you to know not only some information specific to your web server, but also giving you insight on who is visiting your site, with what kind of browser, how they're accessing your program among other useful information.
