[dancer-users] Client IP addr from behind a proxy

Hi all,

Fairly new user here...

I've got a server that sits on our LAN behind a SonicWall firewall.  Our Dancer2  application 
is running on port 8080 and is being reverse proxied by Apache.

Yuck, I know.

So, I'd like to get the actual client's IP address for logging purposes.  To test that, I've got 
these lines in my program:

session->write("CLIENT_IP", request->remote_address);
session->write("FORWARD_IP", request->header('x-forwarded-for'));
session->write("REAL_IP", request->header('x-real-ip'));

These tests were based on a few Google searches.

What I find in my session is: (sanitized)

FORWARD_IP: 98.101.x.y

However, my address is  The 98.101.x.y address is our outward facing IP 
address on the SonicWall.

The Apache config resembles:

<Location "/Apps/">
 	ProxyPass ""

So, is what I'm wanting to do even possible in this configuration?  If so, how?

Thanks in advance,

Mike Diehl
