CGI
Common Gateway
Interface: A protocol that allows a Web page to run a program on a
Web server. Forms, counters, and guestbooks are common examples of
CGI programs.
Client
A program (or
software) used to interact with a server. A Web browser is a specific kind of client.
Cookie
A cookie is a piece
of information sent to a browser
by a Web server upon accessing a Web site. The next time the browser
accesses that site, the server retrieves the information. This is
how some Web pages "remember" your previous visits; for example, an
E-Commerce site might use a cookie to remember which items you've
placed in your online shopping cart. Cookies can also store user
preference information, log-in data, etc.
Counter
On the
Web, a counter is a program that counts and typically displays how
many people have visited an HTML page
(usually the home page). Many sites include a counter, either as a matter of
interest or to show that the site is popular. The counter can be
part of the
common gateway interface application that logs and analyzes requests.
At least one company provides the
service of monitoring sites that request it, counting home page
requests, and updating the number of visitors each time the home
page is sent. A third-party who monitors the counting of site
visitors is called an auditor .
