# Response Header'ları { #response-headers }

## Bir `Response` parametresi kullanın { #use-a-response-parameter }

*Path operation function* içinde (cookie'lerde yapabildiğiniz gibi) tipi `Response` olan bir parametre tanımlayabilirsiniz.

Sonra da bu *geçici* response nesnesi üzerinde header'ları ayarlayabilirsiniz.
