Experiments with Apache and CGI git-http-backend behind an nginx load balancing proxy.
The simplest nginx config uses the ngx_http_consistent_hash module to select a backend.
A more powerful nginx config uses the lua-nginx-module to program arbitrarily
complex methods of selecting a backend. See the location ~ ^/lua section of
bin/nginx for one experiment. With ngx.location.capture or lua-resty-redis,
backends can be selected by querying a remote resource, all in a non-blocking
manner.
