/**
 *
 *
 * <pre>
 * 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][google.cloud.tasks.v2.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][google.cloud.tasks.v2.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][Queue.app_engine_routing_override], this value is used for all
 *    tasks in the queue, no matter what the setting is for the [task-level
 *    app_engine_routing][AppEngineHttpRequest.app_engine_routing].
 * The `url` that the task will be sent to is:
 * * `url =` [host][google.cloud.tasks.v2.AppEngineRouting.host] `+`
 *   [relative_uri][google.cloud.tasks.v2.AppEngineHttpRequest.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][google.cloud.tasks.v2.Task.dispatch_deadline]. Failed tasks will
 * be retried according to the [retry
 * configuration][google.cloud.tasks.v2.Queue.retry_config]. `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.
 * </pre>

  /**
   *
   *
   * <pre>
   * 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][google.cloud.tasks.v2.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][google.cloud.tasks.v2.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][Queue.app_engine_routing_override], this value is used for all
   *    tasks in the queue, no matter what the setting is for the [task-level
   *    app_engine_routing][AppEngineHttpRequest.app_engine_routing].
   * The `url` that the task will be sent to is:
   * * `url =` [host][google.cloud.tasks.v2.AppEngineRouting.host] `+`
   *   [relative_uri][google.cloud.tasks.v2.AppEngineHttpRequest.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][google.cloud.tasks.v2.Task.dispatch_deadline]. Failed tasks will
   * be retried according to the [retry
   * configuration][google.cloud.tasks.v2.Queue.retry_config]. `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.
   * </pre>
   *
   * Protobuf type {@code google.cloud.tasks.v2.AppEngineHttpRequest}

     *   For example, `Content-Type` can be set to `"application/json"`.
     * * `Content-Length`: This is computed by Cloud Tasks. This value is
     *   output only.   It cannot be changed.
     * The headers below cannot be set or overridden:
     * * `Host`
     * * `X-Google-*`
     * * `X-AppEngine-*`
     * In addition, Cloud Tasks sets some headers when the task is dispatched,

     * [request
     * headers](https://cloud.google.com/tasks/docs/creating-appengine-handlers#reading_request_headers).

     * Repeated headers are not supported but a header value can contain commas.
     * Cloud Tasks sets some headers to default values:
     * * `User-Agent`: By default, this header is
     *   `"AppEngine-Google; (+http://code.google.com/appengine)"`.
     *   This header can be modified, but Cloud Tasks will append
     *   `"AppEngine-Google; (+http://code.google.com/appengine)"` to the
     *   modified `User-Agent`.
     * If the task has a [body][google.cloud.tasks.v2.AppEngineHttpRequest.body],
     * Cloud Tasks sets the following headers:
     * * `Content-Type`: By default, the `Content-Type` header is set to

     *   setting `Content-Type` to a particular media type when the
     *   [task is created][google.cloud.tasks.v2.CloudTasks.CreateTask].
     *   For example, `Content-Type` can be set to `"application/json"`.
     * * `Content-Length`: This is computed by Cloud Tasks. This value is
     *   output only.   It cannot be changed.
     * The headers below cannot be set or overridden:
     * * `Host`
     * * `X-Google-*`
     * * `X-AppEngine-*`
     * In addition, Cloud Tasks sets some headers when the task is dispatched,
     * such as headers containing information about the task; see
     * [request
     * headers](https://cloud.google.com/tasks/docs/creating-appengine-handlers#reading_request_headers).
