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.

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。

	hdr := r.opts.HeaderSize // remaining header bytes
	var tokens int           // number of tokens to request

	if hdr > 0 { // available tokens go towards header first
		if hdr < b { // all of header can be accommodated
			r.opts.HeaderSize = 0
			need = int(math.Min(float64(b-hdr), float64(need))) // use remaining tokens towards payload
			tokens = need + hdr
		} else { // part of header can be accommodated
			r.opts.HeaderSize -= b - 1

///

## Пользовательские HTTP-заголовки { #custom-headers }

Помните, что собственные проприетарные заголовки можно добавлять, [используя префикс `X-`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

由于 `Response` 经常用于设置头部和 cookies，**FastAPI** 还在 `fastapi.Response` 中提供了它。

///

## 自定义头部 { #custom-headers }

请注意，可以通过[使用 `X-` 前缀](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers)添加自定义专有头部。
