この場合、ミドルウェアはリクエストを横取りし、適切なCORSヘッダーと共に情報提供のために `200` または `400` のレスポンスを返します。

### シンプルなリクエスト

`Origin` ヘッダーのあるリクエスト。この場合、ミドルウェアは通常どおりリクエストに何もしないですが、レスポンスに適切なCORSヘッダーを加えます。

/// note | 技術詳細

 *  Fix: Limit retry attempts for HTTP/2 `REFUSED_STREAM` and `CANCEL` failures.
 *  Fix: Retry automatically when incorrectly sharing a connection among multiple hostnames. OkHttp
    shares connections when hosts share both IP addresses and certificates, such as `squareup.com`
    and `www.squareup.com`. If a server refuses such sharing it will return HTTP 421 and OkHttp will
    automatically retry on an unshared connection.
