**FastAPI** verwendet diese *vorübergehende* Response, um die Header (auch Cookies und Statuscode) zu extrahieren und fügt diese in die endgültige Response ein, die den von Ihnen zurückgegebenen Wert enthält, gefiltert nach einem beliebigen `response_model`.

Sie können den Parameter `Response` auch in Abhängigkeiten deklarieren und darin Header (und Cookies) festlegen.
