Sharing websocket across browser tabs?

Question

We want to have one socket per browser rather than one per tab in a browser. How can we achieve it? I read about shared web workers which was promising. A reference for that

Answer 1

I used the localStorage object for communication between tabs in some occasions. The localStorage object has an event system to tell another tab or window of the same origin that some data has changed ( http://www.codediesel.com/javascript/sharing-messages-and-data-across-windows-using-localstorage/ ). The idea is, to let the tab with the socket write a timestamp and the received data into the localstorage. If the timestamp gets too old - maybe because the tab with the socket has been closed - another tab can start a socket-connection and update the data and timestamp.
