<title>What is a proxy server?</title>
<para>A proxy server is a server (a computer system or an application) that acts
as an intermediary for requests from clients seeking resources from other
servers. A client connects to the proxy server, requesting some service,
such as a file, connection, web page, or other resource available from a
different server and the proxy server evaluates the request as a way to
simplify and control its complexity. (From Wikipedia)</para>
