But a "Web server" is also the
software program on that computer that fills requests for
Web pages. In fact, a host computer may have several web
server programs "running" on it. Those programs can serve
several web sites, each with its own domain name.
In this tutorial, when we say "Web
server" we simply mean the thing that receives and fills
requests. It's a program, it's on a computer, but what's
important to us is what it does .
And, as a matter of fact, what it
does goes beyond sending Web pages. It also provides a
gateway to other software programs on its host computer,
making it possible for a Web site to go well beyond the
simple model of the printed page.
