HTTP server
<World-Wide Web> (Or "web server") A
server process running at a
web site which sends out web pages in response to
HTTP requests from remote browsers.
If one site runs more than one server they must use different port numbers.
Alternatively, several hostnames may be mapped to the same computer in which case they are known as "virtual servers".
Apache and
NCSA HTTPd are two popular web servers. There are many others including some for practically every
platform.
Servers differ mostly in the "server-side" features they offer such as
server-side include, and in their
authentication and access control mechanisms.
All decent servers support
CGI and most have some binary
API as well.
