A proxy server is a computer system or router that acts as a relay between a client and server, aiding in preventing attackers from invading a private network. The server receives all requests, processes them before sending them to the Internet, and then receives the responses before sending them back to the user. It is used to construct a firewall, and acts on behalf of the user, which is the meaning of the term “proxy.”
