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.

Here we use it to create a `GzipRequest` from the original request.

func sipHashMod(key string, cardinality int, id [16]byte) int {
        if cardinality <= 0 {
                return -1
        }
        sip := siphash.New(id[:])
        sip.Write([]byte(key))
        return int(sip.Sum64() % uint64(cardinality))
}
```

Instead, deferred functions are invoked immediately before
the surrounding function returns, in the reverse order
they were deferred. That is, if the surrounding function
returns through an explicit <a href="#Return_statements">return statement</a>,
deferred functions are executed <i>after</i> any result parameters are set
by that return statement but <i>before</i> the function returns to its caller.
If a deferred function value evaluates

* Uma função `call_next` que receberá o `request` como um parâmetro.
    * Esta função passará a `request` para a *operação de rota* correspondente.
    * Então ela retorna a `response` gerada pela *operação de rota* correspondente.
* Você pode então modificar ainda mais o `response` antes de retorná-lo.

- Client sends HTTP `POST` request over a TLS connection hitting the MinIO TLS STS API.
- MinIO verifies that the client certificate is valid.
- MinIO tries to find a policy that matches the `CN` of the client certificate.
- MinIO returns temp. S3 credentials associated to the found policy.
