title: Get active Websockets of a Website possible?
body: <p>I would like to know if its possible to get active WebSockets of a Website.
  An example would be: <code>var x = document.findWebSocket()</code>. 
  The websockets would be listed in Chrome under the Network Tab (In the dev tools section). From there the websockets are listed under "WS". I want to be able to do <code>x.emit(..);</code> as well.</p>
  
  <p>So far i could only come up with <code>var x = new WebSocket("wss://exampleUrl.com/socket.io/?EIO=3&amp;transport=websocket", "protocol1");</code>. But this only adds a new Websocket with a different sid from the one that i want to emit messages from.</p>
  
  <p>adding "&amp;sid = {SID of Active Websocket}" would not work.</p>
