*  **Proxy authenticators are now asked for preemptive authentication.** OkHttp will now request
    authentication credentials before creating TLS tunnels through HTTP proxies (HTTP `CONNECT`).
    Authenticators should identify preemptive authentications by the presence of a challenge whose
    scheme is "OkHttp-Preemptive".

          assertThat(response.request.url.host).isEqualTo("android.com")
          val challenges = response.challenges()
          assertThat(challenges[0].scheme).isEqualTo("OkHttp-Preemptive")
          response.request
            .newBuilder()
            .header("Proxy-Authorization", credential)
            .build()
        }.build()
