Thanks, but no.<br>

The graceful exit process is expected to handle all existing <br>
connections till they are closed normally. This includes <br>
Websocket connections.<br>
<br>
The recommended approach for long-running connections (including <br>
Websocket, stream module connections, or just long-running HTTP <br>
requests) is to close them periodically from the server side, so <br>
they can be properly re-established without errors.<br>
<br>
If this does not work for you for some reason (for example, if you <br>
cannot control the behaviour of the backend server), consider <br>
using the "worker_shutdown_timeout" directive<br>
(<a href="http://nginx.org/r/worker_shutdown_timeout" rel="noreferrer" target="_blank">http://nginx.org/r/worker_shutdown_timeout</a>) to terminate all <br>
connections after certain period of time. <br>
