File responses will include appropriate `Content-Length`, `Last-Modified` and `ETag` headers.

You can also use the `response_class` parameter:

* `filename` – Wenn gesetzt, wird das in der `Content-Disposition` der Response eingefügt.

Datei-Responses enthalten die entsprechenden `Content-Length`-, `Last-Modified`- und `ETag`-Header.

Sie können auch den Parameter `response_class` verwenden:
