# Hintergrundtasks

Sie können Hintergrundtasks (Hintergrund-Aufgaben) definieren, die *nach* der Rückgabe einer Response ausgeführt werden sollen.

Das ist nützlich für Vorgänge, die nach einem Request ausgeführt werden müssen, bei denen der Client jedoch nicht unbedingt auf den Abschluss des Vorgangs warten muss, bevor er die Response erhält.

Hierzu zählen beispielsweise:

* E-Mail-Benachrichtigungen, die nach dem Ausführen einer Aktion gesendet werden:

flagged as a TODO by the automated tooling. That is true even for proposals that add API.

Use the following forms in your markdown:

	[http.Request]                     # symbol documentation; auto-linked as in Go doc strings
	[Request]                          # short form, for symbols in the package being documented
	[net/http]                         # package link
	[#12345](/issue/12345)             # GitHub issues

```

würden wir dieses Objekt für jeden Request erstellen und die `.env`-Datei für jeden Request lesen. ⚠️

Da wir jedoch den `@lru_cache`-Dekorator oben verwenden, wird das `Settings`-Objekt nur einmal erstellt, nämlich beim ersten Aufruf. ✔️
