# Headers de Respuesta

## Usar un parámetro `Response`

Puedes declarar un parámetro de tipo `Response` en tu *función de operación de path* (de manera similar como se hace con las cookies).

Y entonces, podrás configurar las cookies en ese objeto de response *temporal*.

- `LabelSelectors` specified in `topologySpreadConstraints` were validated to ensure that pods are scheduled as expected. Existing pods with invalid `LabelSelectors` could be updated, but new pods were required to specify valid `LabelSelectors`.
