I am looking for a way to correctly display a web page as a response to get query in express node.js while the server waits for a secondary event to happen. This will be very much like merchant transaction where the client shows "waiting page" where in server authenticates and then take the user back to actual page.
I have tried to use socket.io, however I doubt if its right approach, as this is more of point to point instead of pub-sub mode.
Thanks for your contribution. I would also like to ensure the approach can scale across multiple node process.
