      1. Set `proxy-address-forwarding="true"` on http-listener:
      2. Deploy jsp that logs out request.getServerName/getServerPort/etc.
      3. Make request with X-Forwarded-* headers present:

      # curl -H "X-Forwarded-Host:myhost" -H "X-Forwarded-Port: 80" http://localhost:8080/sample_proxynameport/hello.jsp
request.getServerName() => localhost
request.getServerPort() => 8080
request.getScheme()     => http
      Show
      1. Set `proxy-address-forwarding="true"` on http-listener: 2. Deploy jsp that logs out request.getServerName/getServerPort/etc. 3.

      If I configure `proxy-address-forwarding` for my http-listener, reqeust.getServerName and request.getServerPort still return the hostname/port from the Host header in the request. I would expect if `proxy-address-forwarding` is configured that the Apache proxy's hostname/port would be returned.

      I noticed that when I make a curl request with an empty Host header (like below) that the X-Forwarded-* headers are picked up by getServerName/getServerPort.

      Whereas, if I set Host header to empty it works:

      # curl -H "Host:" -H "X-Forwarded-Host:myhost" -H "X-Forwarded-Port: 80" http://localhost:8080/sample_proxynameport/hello.jsp
request.getServerName() => myhost
request.getServerPort() => 80
request.getScheme()     => http

      However, not having a Host header is bad HTTP/1.1 and in future Undertow release the "workaround" above will not work (UNDERTOW-786).
