x-forwarded-for

We have IIS7 servers sitting behind an nginx reverse proxy.

The reverse proxy is sending the standard "HTTP_X_FORWARDED_FOR" header with the visitor IP address, but IIS7 logging is only logging the IP address of the nginx server (which makes sense, but it's not what I want).

How can I tell IIS7 to instead log the "HTTP_X_FORWARDED_FOR" header (or additionally log it)?

(note: I'm a linux admin, not a windows one, so explicit instructions & links are sincerely appreciated)
