In diesem speziellen Beispiel wäre das nicht so wichtig, weil es sich um eine unechte In-Memory-Datei (mit `io.BytesIO`) handelt, aber bei einer echten Datei wäre es wichtig sicherzustellen, dass die Datei nach der Arbeit damit geschlossen wird.

Puis, juste après le `yield`, nous déchargeons le modèle. Ce code sera exécuté **après** que l'application **a fini de traiter les requêtes**, juste avant l'*arrêt*. Cela pourrait, par exemple, libérer des ressources comme la mémoire ou un GPU.

/// tip | Astuce

Le `shutdown` se produit lorsque vous **arrêtez** l'application.

Peut-être devez-vous démarrer une nouvelle version, ou vous en avez simplement assez de l'exécuter. 🤷

En la mayoría de los casos tendrías (y deberías) tener un "proxy de terminación" manejando HTTPS por ti, esto dependerá de cómo despliegues tu aplicación, tu proveedor podría hacer esto por ti, o podrías necesitar configurarlo tú mismo.

/// tip

The app above is a minimal and simple example to demonstrate how to handle and broadcast messages to several WebSocket connections.

But keep in mind that, as everything is handled in memory, in a single list, it will only work while the process is running, and will only work with a single process.
