I use nginx as a reverse proxy in front of our application web server (gunicorn; it's a Django app). Majority of the users hitting this web application are actually routed through a forward proxy.
Since requests pass through the forward proxy's servers, the IP address in these cases is always from proxy servers instead of from the original requestor. I want to rectify this situation.
All requests originating from the forward proxy contain a header
via:proxy. In such requests, the original requestor IP is sent in a separate HTTP header field called
X-IORG-FBS-UIP (and also
My question is, how can I configure nginx such that it detects whether the request has
via:proxy header, and if so, logs the original requestor IP from the
X-IORG-FBS-UIP header? An illustrative example would be great; thanks in advance! My nginx is v 1.4.6
Note that I do not have the IP ranges used by the forward proxy. If I did, one way to solve this problem would been setting up
set_real_ip_from 188.8.131.52/22; set_real_ip_from 184.108.40.206/22; real_ip_header X-IORG-FBS-UIP;
