re: getServerPort always return 80

[王 静凯]

Hi,
       I have try proxyName and proxyPort, but the proxyPort can change nothing 
when proxyName can take effect.

>>>  Probably your Tomcat listens on Port 80 and nginx was sending the request 
>>> to that port.
      My tomcat listen 8080 and nginx listen 81, nginx sent the request to 8080 
with a host header �C ‘ip:81’
     According to the definition of getServerPort : ‘It is the value of the 
part after ":" in the Host header value, if any’
