Hi,

I have a HAProxy running in front of Nginx, and I add 'X-Client-IP' header to reflect the actual IP of the client. If the request is routed directly to the application server (Tornado in my case), this header is present and I can retrieve it with no problem.

However, if the request is first routed to Nginx and then to the application server using:

proxy_pass http://127.0.0.1:8080;
proxy_redirect off;

then the 'X-Client-IP' header is missing from the request when it reaches Tornado. I guess I might need to explicitly add this header in Nginx as well, so it can relay it on. What is the right solution here?
