In your application, you may be using YARP, to build a reverse proxy gateway sitting in front of various backend applications. For example, you may run YARP to listen on example.org, and have it proxy all requests going to this domain while mapping /api and /docs to different web apps running on diffreent servers.

I hope you left feedback!
