title: reuse socket id on reconnect, socket.io, node.js
body: <p>is it possible to reuse a socket.id or use it multiple times?</p>
  
  <p>Let's assume a user views multiple pages of the same site in different browser tabs. I want to use a single socket.id, socket to handle them all.</p>
  
  <p>If a user receives a notification it should popup on all tabs with a single socket.emit.</p>
