* Распаковка тел запросов, сжатых с помощью gzip.
* Автоматическое логирование всех тел запросов.

## Обработка пользовательского кодирования тела запроса { #handling-custom-request-body-encodings }

Посмотрим как использовать пользовательский подкласс `Request` для распаковки gzip-запросов.

И подкласс `APIRoute`, чтобы использовать этот пользовательский класс запроса.

Maneja responses GZip para cualquier request que incluya `"gzip"` en el header `Accept-Encoding`.

El middleware manejará tanto responses estándar como en streaming.
