/// tip | Dica

Tenha em mente que cabeçalhos proprietários personalizados podem ser adicionados <a href="https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers" class="external-link" target="_blank">usando o prefixo 'X-'</a>.

Pero puedes devolver un `JSONResponse` directamente desde tus *path operations*.

Esto podría ser útil, por ejemplo, para devolver headers o cookies personalizados.

## Devolver una `Response`

De hecho, puedes devolver cualquier `Response` o cualquier subclase de ella.

/// tip | Consejo

`JSONResponse` en sí misma es una subclase de `Response`.

If you are running your container behind a TLS Termination Proxy (load balancer) like Nginx or Traefik, add the option `--proxy-headers`, this will tell Uvicorn (through the FastAPI CLI) to trust the headers sent by that proxy telling it that the application is running behind HTTPS, etc.

```Dockerfile
CMD ["fastapi", "run", "app/main.py", "--proxy-headers", "--port", "80"]
```
