Accessing client's address when using uWSGI protocol

[krzysdz]

When using a HTTP proxy, client's IP address is usually obtained from X-Forwarded-For that is set by proxy. With uWSGI the address is passed by proxy (nginx) as REMOTE_ADDR and REMOTE_PORT params, but there does not seem to be a way to access it and the REMOTE_ADDR and REMOTE_PORT received by the WSGI app point to proxy (or nothing if a unix socket is used).

Do I have to add X-Forwarded-For even with uWSGI? The docs don't mention it, so one would think that the basic configuration should be enough.
