Web Sockets give you full-duplex functionality with a single connection between the client and server. Full-duplex allows messages to be passed in both directions at the same time. HTTP is half-duplex where data can only be passed in one direction at a time. For example, the server cannot respond to a client request until it has finished receiving the request. A Web Socket connection can also remain open for the life of the session.The other nice thing about Web Sockets is that they operate over port 80/443 so there are no firewall or proxy issues to contend with
