For example:

```Python
app.add_middleware(MiddlewareA)
app.add_middleware(MiddlewareB)
```

This results in the following execution order:

* **Request**: MiddlewareB → MiddlewareA → route

* **Response**: route → MiddlewareA → MiddlewareB

This stacking behavior ensures that middlewares are executed in a predictable and controllable order.

## Other middlewares { #other-middlewares }

De la même façon qu'il existe `Query` et `Path` pour définir des données supplémentaires pour les paramètres query et path, **FastAPI** fournit un équivalent `Body`.

Par exemple, en étendant le modèle précédent, vous pouvez vouloir ajouter un paramètre `importance` dans le même body, en plus des paramètres `item` et `user`.

        auth.setForceFallback(true);

        // Token advertising Kerberos mech (so foundKerberos == true), but forceFallback should still route to NTLM
        byte[] init = spnegoInitWithMechs(Kerb5Context.SUPPORTED_MECHS);

        // NtlmPasswordAuthenticator#createContext will inspect mechs and throw because NTLM is not advertised

## À propos des versions

Suivant les conventions de versionnage sémantique, toute version inférieure à `1.0.0` peut potentiellement ajouter
des changements non rétrocompatibles.

FastAPI suit également la convention que tout changement de version "PATCH" est pour des corrections de bogues et
des changements rétrocompatibles.

### Headings

1) Prefer translating headings using the infinitive form (as is common in the existing French docs): «Créer…», «Utiliser…», «Ajouter…».

2) For headings that are instructions written in imperative in English (e.g. “Go check …”), keep them in imperative in French, using the formal grammar (e.g. «Allez voir …»).
