What is a Proxy Server

A proxy server is an intermediary server that acts as a gateway between a client (such as a computer or a mobile device) and the internet.

It serves as a middleman, forwarding requests from the client to other servers on the internet.

When a client requests to access a website or any online resource, the request is first sent to the proxy server, which then retrieves the requested information on behalf of the client.
