Actually What is a Proxy Server:

A proxy server, also known as a "proxy" or "application-level gateway", is a computer that acts as a gateway between a local network (e.g., all the computers at one company or in one building) and a larger-scale network such as the internet. Proxy servers provide increased performance and security. In some cases, they monitor employees' use of outside resources. Read more about Proxy Server
