Mismatching Host and Port being returned from HttpServletRequestImpl methods when Proxy present

HttpRequest.getServerName() and HttpRequest.getServerPort() return mismatching information when a Proxy is present.

HttpRequest.getServerName() will return the Proxy host, as the HttpServerExchange checks the request headers before the destination address.

HttpRequest.getServerPort() will return the server port, as it gets the port from the destination address at all times.
