virtual server
<World-Wide Web> A configuration of a World-Wide Web server that appears
to clients as an independent server but which is actually running on a computer
that is shared by any number of other virtual servers. Each virtual server can
be configured as an independent website, with its own hostname, content, and
security settings.
DNS maps the hostnames of all virtual servers on one physical server to its IP
address. The web server software then uses the "Host" header in the HTTP request
to determine which virtual server the request was for, and then processes the
request using that virtual server's configuration.
Virtual servers allow Internet Service Providers to share one computer between
multiple websites while allowing the owner of each website to use and administer
the server as though they had complete control.
