Pode ser útil para retornar cabeçalhos e cookies personalizados, por exemplo.

## Retornando uma `Response`

Na verdade, você pode retornar qualquer `Response` ou subclasse dela.

/// tip | Dica

A própria `JSONResponse` é uma subclasse de `Response`.

///

E quando você retorna uma `Response`, o **FastAPI** vai repassá-la diretamente.

## Manejo de codificaciones personalizadas de request body

Veamos cómo hacer uso de una subclase personalizada de `Request` para descomprimir requests gzip.

Y una subclase de `APIRoute` para usar esa clase de request personalizada.

### Crear una clase personalizada `GzipRequest`
