This is just conceptual but you could try (if the 'serverX' is like a prefix
for a subdomain):

location ~ /files/(.*)/(.*) {
proxy_pass http://$1.domain.com/$2;
}


This way you just need also to define a resolver (
http://wiki.nginx.org/NginxHttpCoreModule#resolver ) if your hosts are not
defined in upstream{} block or IPs.
