They're also concrete: each URL identifies a specific path (like `/square/okhttp`) and query (like `?q=sharks&lang=en`). Each webserver hosts many URLs.

### [Addresses](https://square.github.io/okhttp/5.x/okhttp/okhttp3/-address/)

Addresses specify a webserver (like `github.com`) and all of the **static** configuration necessary to connect to that server: the port number, HTTPS settings, and preferred network protocols (like HTTP/2).

## `fastapi run` { #fastapi-run }

Exécuter `fastapi run` démarre FastAPI en mode production par défaut.

Par défaut, l’**auto-reload** est désactivé. Il écoute aussi sur l’adresse IP `0.0.0.0`, ce qui signifie toutes les adresses IP disponibles ; de cette manière, il sera accessible publiquement à toute personne pouvant communiquer avec la machine. C’est ainsi que vous l’exécutez normalement en production, par exemple dans un conteneur.

///

### Activer les en-têtes transférés par le proxy { #enable-proxy-forwarded-headers }

Vous pouvez démarrer FastAPI CLI avec l'option de CLI `--forwarded-allow-ips` et fournir les adresses IP à considérer comme fiables pour lire ces en‑têtes transférés.

Si vous la définissez à `--forwarded-allow-ips="*"`, elle fera confiance à toutes les IP entrantes.

    * C'est une couche **en dessous de HTTP**.
    * Donc, la gestion du **certificat et du cryptage** est effectuée **avant HTTP**.
* **TCP ne connaît pas les « domaines »**. Il ne connaît que les adresses IP.
    * L'information sur le **domaine spécifique** demandé se trouve dans les **données HTTP**.
