Google Docs,Microsoft Office 365,IBM Docs,Cisco WebEx,Acrobat,... you
know,when editing online office document,it need WebSocket supporting.
 Especially in online office documents interoperability,when users from
different websites want to Collaborative Editing，it need WebSocket,because
of Comet or Long Polling,just the same as realtime
