Sometimes there's an action required like calling the application layer or responding to a ping, and the thread discovering the action is not the thread that should do the work. We enqueue a runnable on this executor and it gets handled by one of the executor's threads.

### Locks

We have 3 different things that we synchronize on.

#### Http2Connection

# Behind a Proxy { #behind-a-proxy }

In many situations, you would use a **proxy** like Traefik or Nginx in front of your FastAPI app.

These proxies could handle HTTPS certificates and other things.

## Proxy Forwarded Headers { #proxy-forwarded-headers }

### Verwenden Sie das Attribut `app.dependency_overrides`.

Für diese Fälle verfügt Ihre **FastAPI**-Anwendung über das Attribut `app.dependency_overrides`, bei diesem handelt sich um ein einfaches `dict`.

Um eine Abhängigkeit für das Testen zu überschreiben, geben Sie als Schlüssel die ursprüngliche Abhängigkeit (eine Funktion) und als Wert Ihre Überschreibung der Abhängigkeit (eine andere Funktion) ein.
