And as the `Response` can be used frequently to set headers and cookies, **FastAPI** also provides it at `fastapi.Response`.

///

## Custom Headers { #custom-headers }

Keep in mind that custom proprietary headers can be added [using the `X-` prefix](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

また、`Response` はヘッダーや Cookie を設定するのによく使われるため、**FastAPI** は `fastapi.Response` でも提供しています。

///

## カスタムヘッダー { #custom-headers }

独自のカスタムヘッダーは、[`X-` プレフィックスを使って](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers)追加できることに注意してください。

그리고 `Response`는 헤더와 쿠키를 설정하는 데 자주 사용될 수 있으므로, **FastAPI**는 `fastapi.Response`로도 이를 제공합니다.

///

## 커스텀 헤더 { #custom-headers }

커스텀 사설 헤더는 [`X-` 접두어를 사용하여](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers) 추가할 수 있다는 점을 기억하세요.

為了方便開發者，FastAPI 提供與 `starlette.responses` 相同的內容於 `fastapi.responses`。但大多數可用的回應類型其實直接來自 Starlette。

由於 `Response` 常用來設定標頭與 Cookie，FastAPI 也在 `fastapi.Response` 提供了它。

///

## 自訂標頭 { #custom-headers }

請記住，專有的自訂標頭可以[使用 `X-` 前綴](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers)來新增。
