With that you can connect the WebSocket and then send and receive messages:

## Handling disconnections and multiple clients { #handling-disconnections-and-multiple-clients }

When a WebSocket connection is closed, the `await websocket.receive_text()` will raise a `WebSocketDisconnect` exception, which you can then catch and handle like in this example.

Here's a general idea of how the models could look like with their password fields and the places where they are used:

 * Drop ALPN support in Android. There's a concurrency bug in all
   currently-shipping versions.
 * Support asynchronous disconnects by breaking the socket only. This should
   prevent flakiness from multiple threads concurrently accessing a stream.

 * Fix bug where the Content-Length header was not always dropped when
   following a redirect from a POST to a GET.
