# Matches GET and HEAD requests in the format of ":domain.example.com/:dkey"

# If a client were to make a request to "http://foo.example.com/bar",
# this endpoint would respond with the file from the "foo" domain
# with the key "bar".
# To use as middleware:
#    require 'regurgitator'
#    db = Sequel.connect('mysql2://[e-mail]/mogilefs')
#    use Regurgitator::DomainHost, :suffix => '.example.com', :db => db
#
# See the {domain_host.ru}[link:examples/domain_host.ru]
# example for a standalone app.
