Yeah, but you have to admit that children wouldn’t ask you what a reverse proxy is. I tried my best to write short, omitting details and in a simple language.

A reverse proxy delegates HTTP requests to the web servers that should respond. It may also decrypt from HTTPS and/or cache them, it static content is served.

If you are using containers, the web servers running inside the containers are proxied. That means the delegation forwards the requests to the container which web server has to respond to.
