* `allow_credentials` - 교차-출처 요청시 쿠키 지원 여부를 설정합니다. 기본값은 `False` 입니다. 또한 해당 항목을 허용할 경우 `allow_origins` 는 `['*']` 로 설정할 수 없으며, 출처를 반드시 특정해야 합니다.
* `expose_headers` - 브라우저에 접근할 수 있어야 하는 모든 응답 헤더를 가리킵니다. 기본값은 `[]` 입니다.
* `max_age` - 브라우저가 CORS 응답을 캐시에 저장하는 최대 시간을 초 단위로 설정합니다. 기본값은 `600` 입니다.

미들웨어는 두가지 특정한 종류의 HTTP 요청에 응답합니다...

### CORS 사전 요청

`Origin` 및 `Access-Control-Request-Method` 헤더와 함께 전송하는 모든 `OPTIONS` 요청입니다.

| rmdir               | yes       |
| delete              | yes       |
| append              | no        |
| rename              | no        |

MinIO supports following FTP/SFTP based protocols to access and manage data.

- Secure File Transfer Protocol (SFTP) – Defined by the Internet Engineering Task Force (IETF) as an
  extended version of SSH 2.0, allowing file transfer over SSH and for use with Transport Layer

        clearInvocations(transport);
        assertSame(transport, session.getTransport());
        verify(transport, times(1)).acquire();
    }

        SmbSessionImpl session = newSession();

        // First release drops usage to zero and releases transport
        session.release();

* `allow_credentials` - オリジン間リクエストでCookieをサポートする必要があることを示します。デフォルトは `False` です。
* `expose_headers` - ブラウザからアクセスできるようにするレスポンスヘッダーを示します。デフォルトは `[]` です。
* `max_age` - ブラウザがCORSレスポンスをキャッシュする最大時間を秒単位で設定します。デフォルトは `600` です。

このミドルウェアは2種類のHTTPリクエストに応答します...

### CORSプリフライトリクエスト

これらは、 `Origin` ヘッダーと `Access-Control-Request-Method` ヘッダーを持つ `OPTIONS` リクエストです。
