Hi we have used apache as proxy in order to forward HTTP2 request to backend using mod_proxy_http2. We have enable ProxyPreserveHost such that the originally :authority header is preserved. However, we found that the port adress information is removed after proxy. e,g, incoming HTTP2 request to Apache =========================== :authority: test.com:1234 outgoing HTTP2 request from Apache ============================= :authority: test.com is there any method to preserve the port address information?
