      1. Use Undertow to set up a public HTTP server with a ProxyHandler that implements a reverse proxy to an internal server.
      2. Use a web client, with an IP address that looks up to a hostname, to make a request to the reverse proxy
      3. Check the X-Forwarded-For header received on the internal server. It is the text hostname, not the IP address

      I am using Undertow's ProxyHandler to implement a reverse proxy of public client requests to an internal server. The X-Forwarded-For header that the internal server receives has a hostname, not an IP address.
