When you use variables in proxy_pass you have to construct full 
url yourself.  I.e. you should use something like

    proxy_pass http://$host_without_files$request_uri;

Also note: with proxy_pass with variables nginx will be forced to 
resolve backend hostname for each request.  You may want to define 
appropriate upstream{} blocks for servers you are mirroring to 
avoid DNS resolving.

p.s. It's probably good idea to use multiple server{}'s without using 
variables.  This will save some cpu.
