## Rewriting Responses

If transparent compression was used, OkHttp will drop the corresponding response headers `Content-Encoding` and `Content-Length` because they don’t apply to the decompressed response body.

If a conditional GET was successful, responses from the network and cache are merged as directed by the spec.

要查看响应中究竟可以包含什么，你可以查看 OpenAPI 规范中的以下部分：

* [OpenAPI Responses 对象](https://github.com/OAI/OpenAPI-Specification/blob/master/versions/3.1.0.md#responses-object)，它包含 `Response Object`。

      when {
        response != null && response.code != 101 -> response.body.string()
        else -> null
      }
