set arbitrary http header?

There are several nodes in between nginx and apache. It's not internet ->
nginx -> apache.
It's internet -> nginx -> varnish -> haproxy - > apache1
 - >
apache2
 - >
apacheN
So far, everything is in the apache access logs except the IP of the nginx
server connecting.
But you're right, I could just set it manually, for each nginx server. I
might just do that.
And you're also again right that our servers have multiple IPs.
