CGI
(Common Gateway Interface) A CGI is a program that tanslates data

into a web site.
cgi-bin
The most common name of a directory on a web server in which CGI
programs are stored. The “bin” part of “cgi-bin”

In real life, most programs found in cgi-bin directories are text
files -- scripts that are executed by binaries located elsewhere
on the same machine.

regular visitors or customers of your site time from having to log
in and log out every time they visit your site.
