  1. Configuration of Envoy proxies by Pilot.
  1. Communication between Pilot and Envoy proxies.
  1. Validation of service discovery.
  1. Testing of traffic management policies (e.g., routing, retries, timeouts).
  1. Validation of load balancing configurations.
  1. Specific `istioctl proxy-config` commands being tested: `bootstrap`, `cluster`, `endpoint`, `listener`, `route`, `all`.

### Eine benutzerdefinierte `GzipRoute`-Klasse erstellen

Als Nächstes erstellen wir eine benutzerdefinierte Unterklasse von `fastapi.routing.APIRoute`, welche `GzipRequest` nutzt.

Dieses Mal wird die Methode `APIRoute.get_route_handler()` überschrieben.

Diese Methode gibt eine Funktion zurück. Und diese Funktion empfängt einen Request und gibt eine Response zurück.

### Criar uma classe `GzipRoute` personalizada

Em seguida, criamos uma subclasse personalizada de `fastapi.routing.APIRoute` que fará uso do `GzipRequest`.

Dessa vez, ele irá sobrescrever o método `APIRoute.get_route_handler()`.

Esse método retorna uma função. E essa função é o que irá receber uma requisição e retornar uma resposta.

### Create a custom `GzipRoute` class

Next, we create a custom subclass of `fastapi.routing.APIRoute` that will make use of the `GzipRequest`.

This time, it will overwrite the method `APIRoute.get_route_handler()`.

This method returns a function. And that function is what will receive a request and return a response.
