Duplex calls require HTTP/2. If HTTP/1 is established instead the duplex call will fail. The
    most common use of duplex calls is [gRPC][grpc_http2].

 *  New: Prevent OkHttp from retransmitting a request body by overriding `RequestBody.isOneShot()`.
    This is most useful when writing the request body is destructive.

    detecting the TLS capabilities of the host platform.

 *  Fix: Don't crash in `HttpUrl.topPrivateDomain()` when the hostname is malformed.

 *  Fix: Don't attempt Brotli decompression if the response body is empty.


## Version 4.7.2

 *  Fix: Don't crash inspecting whether the host platform is JVM or Android. With 4.7.0 and 4.7.1 we

    /** The key of the configuration. e.g. true */
    String MAIL_SEND_MOCK = "mail.send.mock";

    /** The key of the configuration. e.g. localhost:25 */
    String MAIL_SMTP_SERVER_MAIN_HOST_AND_PORT = "mail.smtp.server.main.host.and.port";

    /** The key of the configuration. e.g. [Test] */
    String MAIL_SUBJECT_TEST_PREFIX = "mail.subject.test.prefix";

    /** The key of the configuration. e.g. root@localhost */

Mas há situações específicas onde é útil utilizar o objeto `Request`.

## Utilize o objeto `Request` diretamente

Vamos imaginar que você deseja obter o endereço de IP/host do cliente dentro da sua *função de operação de rota*.

Para isso você precisa acessar a requisição diretamente.
