5. The daemon sends the result back. For some requests, this might be a simple success/failure result, and for others this might also include a more complex object, such as a tooling API model.

Provided directly by Starlette, but you can import it from `fastapi`:

```python
from fastapi.websockets import WebSocketDisconnect, WebSocketState
```

::: fastapi.websockets.WebSocketDisconnect

When a client disconnects, a `WebSocketDisconnect` exception is raised, you can catch it.

You can import it directly form `fastapi`:

```python
from fastapi import WebSocketDisconnect
```

    assertThat(client.closed).isFalse()

    // Manually write an invalid masked close frame.
    server.sink.write("888760b420bb635c68de0cd84f".decodeHex()).emit()
    client.processNextFrame() // Detects error, disconnects immediately since close already sent.
    client.webSocket!!.finishReader()

## Version 1.5.4

_2014-04-14_

 * 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.

## Version 1.5.3

_2014-03-29_

				w.WriteHeader(499)
				return

			f.ServeHTTP(w, r)
		case <-r.Context().Done():

			// When the client disconnects before getting the S3 handler
			// status code response, set the status code to 499 so this request

			w.WriteHeader(499)
		default:
			globalHTTPStats.addRequestsInQueue(-1)

    different cipher suite than before! OkHttp's defaults cipher suites are selected for good
    security and performance.

 *  New: `ConnectionListener` publishes events for connects, disconnects, and use of pooled
    connections.

 *  Fix: Immediately update the connection's flow control window instead of waiting for the
    receiving stream to process it.
