## Ajouter une tâche d'arrière-plan { #add-the-background-task }

Dans votre *fonction de chemin d'accès*, passez votre fonction de tâche à l'objet de type `BackgroundTasks` (`background_tasks` ici) grâce à la méthode `.add_task()` :

    automatically retry on an unshared connection.
 *  Fix: Don't crash if a TLS tunnel's response body is truncated.
 *  Fix: Don't track unusable routes beyond their usefulness. We had a bug where we could track
    certain bad routes indefinitely; now we only track the ones that could be necessary.
 *  Fix: Defer proxy selection until a proxy is required. This saves calls to `ProxySelector` on

### Qu'est-ce que « Mounting » { #what-is-mounting }

« Mounting » signifie ajouter une application complète « indépendante » sur un chemin spécifique, qui se chargera ensuite de gérer tous les sous-chemins.

The dependency injection system requires pre-registration of the dependencies and the dependencies are solved based on the declared types. So, it's not possible to declare more than one "component" that provides a certain type.
