Hi,
I use httpServletRequest.getServerPort() to get the port in my jsp.
When the tomcat listen 8080 and nginx listen 80.
Nginx has set ‘proxy_set_header Host $http_host’.
What is the value of $http_host?
Then the port 80 mapping to Internet via 10001.
Use httpServletRequest.getHeader(“Host”) I can get the correct value of Host
header – “InternetIP:10001”.
But httpServletRequest.getServerPort() did not return 10001 and return 80.
How could I solve it？
Btw, to set proxyPort in connector can not take effect. But proxyName work.
Have you read about the RemoteIPValve?

getServerPort
int getServerPort()
Returns the port number to which the request was sent. It is the value of the part after
":" in the Host header value, if any, or the server port where the client
connection was accepted on.
Returns:
an integer specifying the port number
Can you dump the values of ALL headers on the Tomcat side and post them?
