In the ever lasting quest of helping users, I have added the following four
headers to imp/config/header.txt:

X-Originating-IP: %REMOTE_ADDR% 
X-Originating-Hostname: %REMOTE_HOST%
X-Proxied-for-IP: %HTTP_X_FORWARDED_FOR%
X-Proxied-via: %HTTP_VIA%

The first two are replaced properly, the second two aren't:
X-Originating-IP: 202.83.176.9
X-Originating-Hostname: proxy.barnet.com.au
X-Proxied-for-IP:
X-Proxied-via:

The four variables are listed in the PHP phpinfo() output under Apache
Environment.

I tried to figure out how the replacement of variables works, but I wasn't
able to make sense of it. That's more a problem from my side than from your
side :-)
