Hi Tanya, according to my understanding this is not an issue with Jaggery but the web socket specification. Since it is intended to provide two-way communication with a remote host the connection should be persistent.
According to [1] "WebSocket connections do not, however, persist across loading of new pages from the same domain, or page reloads. A WebSocket connection only persists as long as the page is still open (not navigated away from)." The initial code snippet call the same page this might be the issue that breaks the code.
