  # ActionController::Instrumentation has issued start_processing.action_controller and
  # process_action.action_controller since Rails 3. Therefore it's a stable place to hook
  # the request. Rails controller notifications can't be used directly because they don't
  # provide response headers, and we want the Content-Type.
