如何从同一台计算机检测多个WebSocket连接？

Question

I have a Node.js WebSocket server and I want to prevent clients from being able to open 50 tabs which will create 50 connections. My current idea is to check the IP addresses like this:

ws._socket.remoteAddress

and then just check that against my current connections IPs and if that IP already exists then reject the connection request. My understanding is that there will be a problem with this approach because if 2 computers are on the same Wifi and therefore have the same public IP, the second computer will be blocked. This isn't what I want. I want 1 connection per computer, therefore IP might not be the solution. Is this a valid problem or would my solution actually work? What is the best way to uniquely identify a client's computer to prevent more than 1 connection on that device?

Answer 1

Assuming you control the clients connecting, I would look at a shared web worker that is used by all tabs in that browser. This would essentially give you 1 connection for n tabs. Each browser would be a new connection though so maybe 3-4 connections at most?

Here is a link. Check out the example as it spells it out pretty succinctly: https://developer.mozilla.org/en-US/docs/Web/API/SharedWorker
