Hi chris,

The $http_host is ‘externalIP:10001’ (I print it in access_log of nginx to
make sure that it is a correct valve.)
I use httpServletRequest.getHeader(“Host”) in java and it can print the
right value too. But as I know the getServerPort should print the number after
‘:’ of ‘Host’ Header.
So I don’t know what’s the wrong.
And today I found another similar situation.
The server has a Internet IP and Tomcat listening 8080 and nginx listening
81. So there are no port mapping.
At this time getServerPort() still return 80.

The RemoteIPValve seems to be used for get the real client IP, but I just
need to get the correct port which client use to visit my website.
Forgive my poor English and I hope you can understand what I say. (＾－＾)
