테스트해보기:

* 여러 브라우저 탭에서 앱을 엽니다.
* 각 탭에서 메시지를 작성합니다.
* 한 탭을 닫아보세요.

`WebSocketDisconnect` 예외가 발생하며, 다른 모든 클라이언트가 다음과 같은 메시지를 수신합니다:

```
Client #1596980209979 left the chat
```

위 응용 프로그램은 여러 WebSocket 연결에 메시지를 브로드캐스트하는 방법을 보여주는 간단한 예제입니다.

그러나 모든 것을 메모리의 단일 리스트로 처리하므로, 프로세스가 실행 중인 동안만 동작하며 단일 프로세스에서만 작동합니다.

     * then it behaves as "ordinary relocation": the coordinate is preserved from relocated artifact.

これにより例外 `WebSocketDisconnect` が発生し、他のすべてのクライアントは次のようなメッセージを受信します。

/// tip | 豆知識

上記のアプリは、複数の WebSocket 接続に対してメッセージを処理し、ブロードキャストする方法を示すための最小限のシンプルな例です。

しかし、すべての接続がメモリ内の単一のリストで処理されるため、プロセスの実行中にのみ機能し、単一のプロセスでのみ機能することに注意してください。
