* Daten verarbeiten:
    * Angenommen, Sie erhalten eine Datei, die einen langsamen Prozess durchlaufen muss. Sie können als Response „Accepted“ (HTTP 202) zurückgeben und die Datei im Hintergrund verarbeiten.

## `BackgroundTasks` verwenden { #using-backgroundtasks }

* `www_redirect` - True로 설정하면, 허용된 호스트의 non-www 버전으로 들어오는 요청을 www 버전으로 리디렉션합니다. 기본값은 `True`입니다.

들어오는 요청이 올바르게 검증되지 않으면 `400` 응답이 전송됩니다.

## `GZipMiddleware` { #gzipmiddleware }

`Accept-Encoding` 헤더에 `"gzip"`이 포함된 어떤 요청이든 GZip 응답을 처리합니다.

이 middleware는 일반 응답과 스트리밍 응답을 모두 처리합니다.
