def call(env)
  @env = env

  if test?
    [ 200, {"Content-Type" => "text/html"}, self ]
  elsif info?
    [ 200, {"Content-Type" => "application/json"}, self ]
  else
    @app.call(env)
  end
end

#each(&block) ⇒ text/html, application/json

Returns text/html when the ‘test` url is requested. This is purely to see whether the URL works through the HireFire command-line utility.

Returns a JSON String when the ‘info` url is requested. This url will be requested every minute by HireFire in order to fetch dyno data.
