    * Para que isso funcione, um único componente (programa) em execução no servidor, ouvindo no endereço IP público, deve ter todos os certificados HTTPS no servidor.
* Depois de obter uma conexão segura, o protocolo de comunicação ainda é HTTP.
    * Os conteúdos são criptografados, embora sejam enviados com o protocolo HTTP.

* **Uvicorn**:
    * Tendrá el mejor rendimiento, ya que no tiene mucho código extra aparte del propio servidor.

Y cuando devuelves una `Response`, **FastAPI** la pasará directamente.

No hará ninguna conversión de datos con modelos Pydantic, no convertirá el contenido a ningún tipo, etc.

Esto te da mucha flexibilidad. Puedes devolver cualquier tipo de dato, sobrescribir cualquier declaración de datos o validación, etc.

## Usando el `jsonable_encoder` en una `Response`
