In limited situations OkHttp will retry a route if connecting fails:

 * When making an HTTPS connection through an HTTP proxy, the proxy may issue an authentication challenge. OkHttp will call the proxy [authenticator](https://square.github.io/okhttp/4.x/okhttp/okhttp3/-authenticator/) and try again.

## Proxy-<abbr title="weitergeleitete Header">Forwarded-Header</abbr> { #proxy-forwarded-headers }

Wenn Sie einen Proxy zur Verarbeitung von HTTPS verwenden, weiß Ihr **Anwendungsserver** (z. B. Uvicorn über das FastAPI CLI) nichts über den HTTPS-Prozess, er kommuniziert per einfachem HTTP mit dem **TLS-Terminierungsproxy**.

   * can't coalesce connections that use a proxy, since proxies don't tell us the origin server's IP
   * address.
