That's sad because it's also nginx.conf's most useful feature. e.g.

if ($request_uri ~* '^/chatSub/(\d+)/$') {
set $backEndDigit $1;
}

proxy_pass http://10.1.0.$backEndDigit:80/someUrl/:

I run this in production with over 30,000 concurrent connections on the 
nginx front end. nginx.conf laughs at apache2.conf and hits on it's 
girlfriend.
