## Connection Pool

A primary responsibility for any HTTP client is to efficiently manage network connections. Creating and establishing new connections require a fair amount of overhead and added latency. OkHttp will make every effort to reuse existing connections to avoid this overhead and added latency.

# 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).

**FastAPI** bietet mehrere Tools auf unterschiedlichen Abstraktionsebenen zur Implementierung dieser Sicherheitsfunktionen.

In diesem Beispiel verwenden wir **OAuth2** mit dem **Password**-Flow und einem **Bearer**-Token. Wir machen das mit der Klasse `OAuth2PasswordBearer`.

/// info

Ein „Bearer“-Token ist nicht die einzige Option.

Aber es ist die beste für unseren Anwendungsfall.

Using the **SNI extension** discussed above, the TLS Termination Proxy would check which of the TLS (HTTPS) certificates available it should use for this connection, using the one that matches the domain expected by the client.

In this case, it would use the certificate for `someapp.example.com`.
