A reverse proxy is used to sit in front of one or more backend servers and handle client requests on their behalf. It is commonly used for security, load balancing, caching, and making sites more reliable and faster

Simple example

If you run several web servers for the same site, users connect to the reverse proxy first, and the proxy decides which backend should handle the request. That lets you scale the site without exposing your internal servers directly.

For an OpenWrt or home-lab setup, a reverse proxy is often the clean way to publish multiple services under one IP and one domain while keeping the internal services isolated
