Perlbal talks to your webserver, then your webserver talks to your tracker
(mogilefsd) or memcached (which has the results of get_paths), and your
webserver replies to Perlbal with the locations of the files in MogileFS
mogstored node(s), optionally telling Perlbal to cache that mapping
internally (Perlbal can internally cache a URL -> @locations for 'n'
seconds).
