 *  **Cache improvements.** This release fixes some severe cache problems
    including a bug where the cache could be corrupted upon certain access
    patterns. We also fixed a bug where the cache was being cleared due to a
    corrupted journal. We've added APIs to configure a request's `Cache-Control`
    headers, and to manually clear the cache.

# Hinter einem Proxy

In manchen Situationen müssen Sie möglicherweise einen **Proxy**-Server wie Traefik oder Nginx verwenden, mit einer Konfiguration, die ein zusätzliches Pfadpräfix hinzufügt, das von Ihrer Anwendung nicht gesehen wird.

In diesen Fällen können Sie `root_path` verwenden, um Ihre Anwendung zu konfigurieren.

Der `root_path` („Wurzelpfad“) ist ein Mechanismus, der von der ASGI-Spezifikation bereitgestellt wird (auf der FastAPI via Starlette aufbaut).
