As code duplication increments the chances of bugs, security issues, code desynchronization issues (when you update in one place but not in the others), etc.

And these models are all sharing a lot of the data and duplicating attribute names and types.

We could do better.

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。

    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.
