The main constraint to consider is that there has to be a **single** component handling the **port** in the **public IP**. And then it has to have a way to **transmit** the communication to the replicated **processes/workers**.

Here are some possible combinations and strategies:

* **Uvicorn** with `--workers`

/// tip | 豆知識

クエリ `token` は依存関係によって処理されることに注意してください。

///

これにより、WebSocketに接続してメッセージを送受信できます。

## 切断や複数クライアントの処理 { #handling-disconnections-and-multiple-clients }

WebSocket接続が閉じられると、 `await websocket.receive_text()` は例外 `WebSocketDisconnect` を発生させ、この例のようにキャッチして処理することができます。

Exception yakalayıp buna göre özel bir response oluşturmak istiyorsanız bir [Custom Exception Handler](../handling-errors.md#install-custom-exception-handlers) oluşturun.

/// tip | 팁

쿼리 `token`은 종속성에 의해 처리됩니다.

이렇게 하면 WebSocket에 연결하고 메시지를 전송 및 수신할 수 있습니다:

<img src="/img/tutorial/websockets/image05.png">

## 연결 해제 및 다중 클라이언트 처리 { #handling-disconnections-and-multiple-clients }

WebSocket 연결이 닫히면, `await websocket.receive_text()`가 `WebSocketDisconnect` 예외를 발생시킵니다. 그러면 이 예제처럼 이를 잡아 처리할 수 있습니다.

До **FastAPI** 0.106.0 піднімати винятки після `yield` було неможливо: завершальний код у залежностях з `yield` виконувався після надсилання відповіді, тож [обробники винятків](../tutorial/handling-errors.md#install-custom-exception-handlers) уже відпрацювали б.
