| A proxy server is a
computer that offers a computer network service to allow clients
to make indirect network connections to other network services.
A client connects to the proxy server, then requests a connection,
file, or other resource available on a different server. The proxy
provides the resource either by connecting to the specified server
or by serving it from a cache. In some cases, the proxy may alter
the client's request or the server's response for various purposes.
A common proxy application is a caching Web proxy or unblockers
as some call them. This provides a nearby cache of Web pages and
files available on remote Web servers, allowing local network
clients to access them more quickly or reliably.
