HTTP or "HyperText Transport Protocol" is
a communication protocol that is used to request and transmit files over
the Internet and other networks. It is the primary method for
exchanging information over the world wide web. Because most
web browsers default to the HTTP protocol, it is normally not necessary
to enter "HTTP://" when requesting a web page.
In response to a HTTP request from a web browser, the web server
responds by returning a status code (e.g. "200 OK") and one or more
requested files (e.g. html pages, graphics, scripts, applets) that the
web browser can then assemble to display a web page.
