Explain what a proxy server does.
What will be an ideal response?
It is best to explain this using a specific type of proxy server—an HTTP proxy server. A proxy server redirects all client requests for HTTP or HTTPS. The proxy server forwards Web client requests to Web servers, and forwards the returning packets to the requesting client. Therefore, the client is never directly communicating with Web servers on the Internet.
