## En-têtes personnalisés { #custom-headers }

Gardez à l'esprit que des en-têtes propriétaires personnalisés peuvent être ajoutés [en utilisant le préfixe `X-`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

Y como el `Response` se puede usar frecuentemente para establecer headers y cookies, **FastAPI** también lo proporciona en `fastapi.Response`.

///

## Headers Personalizados { #custom-headers }

Ten en cuenta que los headers propietarios personalizados se pueden agregar [usando el prefijo `X-`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

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).

        final SystemHelper helper1 = new SystemHelper() {
            @Override
            public long getCurrentTimeAsLong() {
                return systemHelper.eolTime + 1000L;
            }
        };
        helper1.eolTime = systemHelper.eolTime;
        assertTrue(helper1.isEoled());
        final SystemHelper helper2 = new SystemHelper() {
            @Override

Ayrıca `Response` header ve cookie ayarlamak için sık kullanıldığından, **FastAPI** bunu `fastapi.Response` altında da sağlar.

///

## Özel Header'lar { #custom-headers }

Özel/proprietary header'ların [`X-` prefix'i kullanılarak](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers) eklenebileceğini unutmayın.

///

## Cabeçalhos personalizados { #custom-headers }

Tenha em mente que cabeçalhos personalizados proprietários podem ser adicionados [usando o prefixo `X-`](https://developer.mozilla.org/en-US/docs/Web/HTTP/Headers).

///

## 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。
