Единственное, что делает по-другому функция, возвращённая `GzipRequest.get_route_handler`, — преобразует `Request` в `GzipRequest`.

Благодаря этому наш `GzipRequest` позаботится о распаковке данных (при необходимости) до передачи их в наши *операции пути*.

Дальше вся логика обработки остаётся прежней.
