Unix domain sockets are *not* network sockets:

http://en.wikipedia.org/wiki/Unix_domain_socket

They work on localhost only. You will need to use HTTP proxying or
FastCGI.

Probably what you want to do is run an Nginx instance on each backend
server to communicate over the local socket to your app and then proxy
to those Nginx instances from your main Nginx instance over HTTP.
