      # App Engine HTTP request.
      # The message defines the HTTP request that is sent to an App Engine app when
      # the task is dispatched.
      # Using AppEngineHttpRequest requires
      # [`appengine.applications.get`](https://cloud.google.com/appengine/docs/admin-
      # api/access-control)
      # Google IAM permission for the project
      # and the following scope:
      # `https://www.googleapis.com/auth/cloud-platform`
      # The task will be delivered to the App Engine app which belongs to the same
      # project as the queue. For more information, see
      # [How Requests are
      # Routed](https://cloud.google.com/appengine/docs/standard/python/how-requests-
      # are-routed)
      # and how routing is affected by
      # [dispatch
      # files](https://cloud.google.com/appengine/docs/python/config/dispatchref).
      # Traffic is encrypted during transport and never leaves Google datacenters.
      # Because this traffic is carried over a communication mechanism internal to
      # Google, you cannot explicitly set the protocol (for example, HTTP or HTTPS).
      # The request to the handler, however, will appear to have used the HTTP
      # protocol.
      # The AppEngineRouting used to construct the URL that the task is
      # delivered to can be set at the queue-level or task-level:
      # * If app_engine_routing_override is set on the
      # queue, this value is used for all
      # tasks in the queue, no matter what the setting is for the task-level
      # app_engine_routing.
      # The `url` that the task will be sent to is:
      # * `url =` host `+`
      # relative_uri
      # Tasks can be dispatched to secure app handlers, unsecure app handlers, and
      # URIs restricted with
      # [`login:
      # admin`](https://cloud.google.com/appengine/docs/standard/python/config/appref).
      # Because tasks are not run as any user, they cannot be dispatched to URIs
      # restricted with
      # [`login:
      # required`](https://cloud.google.com/appengine/docs/standard/python/config/
      # appref)
      # Task dispatches also do not follow redirects.
      # The task attempt has succeeded if the app's request handler returns an HTTP
      # response code in the range [`200` - `299`]. The task attempt has failed if
      # the app's handler returns a non-2xx response code or Cloud Tasks does
      # not receive response before the deadline. Failed
      # tasks will be retried according to the
      # retry configuration. `503` (Service Unavailable) is
      # considered an App Engine system error instead of an application error and
      # will cause Cloud Tasks' traffic congestion control to temporarily throttle
      # the queue's dispatches. Unlike other types of task targets, a `429` (Too Many
      # Requests) response from an app handler does not cause traffic congestion
      # control to throttle the queue.

      # rate limits, and the queue's state.
      # * System throttling: To prevent the worker from overloading, Cloud Tasks may

      # errors is high, Cloud Tasks will use a higher backoff rate. The retry
      # specified in the `Retry-After` HTTP response header is considered.
      # * To prevent traffic spikes and to smooth sudden increases in traffic,
      # dispatches ramp up slowly when the queue is newly created or idle and
      # if large numbers of tasks suddenly become available to dispatch (due to
      # spikes in create task rates, the queue being unpaused, or many tasks
