Just curious to know, what technology WhatApp engineering guys are using for https://web.whatsapp.com/ that work specific to Chrome Browser.

  1. If you sync your mobile to chrome(mirroring) then what protocol they used to get all chat of mobile on Chrome even you are not in same network.

  2. And, if you disconnect your Whatapp from Wifi or Internet, then it throws message called "Phone not connected" though I can see any ajax or websocket call from Chrome Developer Tools.
