Es gibt Situationen, da ist es nützlich, dem HTTP-Error benutzerdefinierte Header hinzufügen zu können, etwa in einigen Sicherheitsszenarien.

Sie müssen das wahrscheinlich nicht direkt in ihrem Code verwenden.

Aber falls es in einem fortgeschrittenen Szenario notwendig ist, können Sie benutzerdefinierte Header wie folgt hinzufügen:

```Python hl_lines="14"
