Erzwingt, dass alle eingehenden Requests einen korrekt gesetzten `Host`-Header haben, um sich vor HTTP-Host-Header-Angriffen zu schützen.

## Crea un SDK de TypeScript { #create-a-typescript-sdk }

Empecemos con una aplicación simple de FastAPI:

{* ../../docs_src/generate_clients/tutorial001_py39.py hl[7:9,12:13,16:17,21] *}

Nota que las *path operations* definen los modelos que usan para el payload del request y el payload del response, usando los modelos `Item` y `ResponseMessage`.

In this case, the original path `/app` would actually be served at `/api/v1/app`.

Even though all your code is written assuming there's just `/app`.

{* ../../docs_src/behind_a_proxy/tutorial001_py39.py hl[6] *}

Um diese zu deaktivieren, setzen Sie deren URLs beim Erstellen Ihrer `FastAPI`-App auf `None`:

{* ../../docs_src/custom_docs_ui/tutorial001_py39.py hl[8] *}

### Die benutzerdefinierten Dokumentationen hinzufügen { #include-the-custom-docs }

Jetzt können Sie die *Pfadoperationen* für die benutzerdefinierten Dokumentationen erstellen.

The first step is to disable the automatic docs, as by default, those use the default CDN.

To disable them, set their URLs to `None` when creating your `FastAPI` app:

{* ../../docs_src/custom_docs_ui/tutorial001_py39.py hl[8] *}

### Include the custom docs { #include-the-custom-docs }

Now you can create the *path operations* for the custom docs.

Тогда исходный путь `/app` фактически будет обслуживаться по адресу `/api/v1/app`.

Хотя весь ваш код написан с расчётом, что путь один — `/app`.

{* ../../docs_src/behind_a_proxy/tutorial001_py39.py hl[6] *}

Para desactivarlos, establece sus URLs en `None` cuando crees tu aplicación de `FastAPI`:

{* ../../docs_src/custom_docs_ui/tutorial001_py39.py hl[8] *}

### Incluye la documentación personalizada { #include-the-custom-docs }

Ahora puedes crear las *path operations* para la documentación personalizada.

O primeiro passo é desativar a documentação automática, pois por padrão, ela usa o CDN padrão.

Para desativá-los, defina suas URLs como `None` ao criar sua aplicação FastAPI:

{* ../../docs_src/custom_docs_ui/tutorial001_py39.py hl[8] *}

### Incluir a documentação personalizada { #include-the-custom-docs }

Agora você pode criar as *operações de rota* para a documentação personalizada.
