# `HTTPConnection` class

When you want to define dependencies that should be compatible with both HTTP and WebSockets, you can define a parameter that takes an `HTTPConnection` instead of a `Request` or a `WebSocket`.

You can import it from `fastapi.requests`:

```python
from fastapi.requests import HTTPConnection
```

OpenAPI также добавила поля `example` и `examples` в другие части спецификации:

* [`Parameter Object` (в спецификации)](https://github.com/OAI/OpenAPI-Specification/blob/main/versions/3.1.0.md#parameter-object), которое использовалось в FastAPI:
    * `Path()`
    * `Query()`
    * `Header()`
    * `Cookie()`

## Événements alternatifs (déprécié) { #alternative-events-deprecated }

/// warning | Alertes

La méthode recommandée pour gérer le *démarrage* et l'*arrêt* est d'utiliser le paramètre `lifespan` de l'application `FastAPI` comme décrit ci-dessus. Si vous fournissez un paramètre `lifespan`, les gestionnaires d'événements `startup` et `shutdown` ne seront plus appelés. C'est soit tout en `lifespan`, soit tout en événements, pas les deux.
