## 切断や複数クライアントへの対応

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。

{* ../../docs_src/websockets/tutorial003.py hl[81:83] *}

試してみるには、

* いくつかのブラウザタブでアプリを開きます。
* それらのタブでメッセージを記入してください。
* そして、タブのうち1つを閉じてください。

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。

```
