In one sentence: A reverse proxy is a server that sits between visitors and a website's actual backend servers, forwarding requests on their behalf and often adding caching, security, or load distribution along the way.

A reverse proxy adds a useful layer of indirection โ€” visitors interact with the proxy, never directly with the real backend servers behind it.

Reverse Proxy vs Forward Proxy

A forward proxy sits in front of clients, hiding their identity from the servers they connect to. A reverse proxy does the opposite โ€” it sits in front of servers, hiding their identity and details from visitors.
