In computer networks, a proxy server is a server (a computer system or an application program) which services the requests of its clients by forwarding requests to 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. The proxy server provides the resource by connecting to the specified server and requesting the service on behalf of the client. A proxy server may optionally alter the client's request or the server's response, and ....etc

The requested resource is provided by the proxy server either from the cache or by fetching from the specified server. In some cases, the client's request or the server's response maybe altered by the proxy server> the purpose for this maybe for vi ....etc
