### Checking the current `root_path`

You can get the current `root_path` used by your application for each request, it is part of the `scope` dictionary (that's part of the ASGI spec).

Here we are including it in the message just for demonstration purposes.

### Überprüfen des aktuellen `root_path`

Sie können den aktuellen `root_path` abrufen, der von Ihrer Anwendung für jede Anfrage verwendet wird. Er ist Teil des `scope`-Dictionarys (das ist Teil der ASGI-Spezifikation).

Hier fügen wir ihn, nur zu Demonstrationszwecken, in die Nachricht ein.
