qlik-cloud-jwt-lambda-example v1.4.0

Hardened the web page sample code to fire an enigma websocket session closure upon the offline event. Recent testing illustrated that in Chromium browsers, going offline (dropping your internet connection or throttling the network to "offline" in dev tools) was not triggering the closed event. Adding in a listener for the offline event which subsequently explicitly closes the websocket handles for this scenario. Browsers such as Firefox appear to be unaffected, though also work with this modification.
