What is WebSocket?

WebSocket is a computer communications protocol that enables messages to be sent to and from the server. Basically, it is a means of communication between you and the server. The WebSocket specification defines an API for establishing "socket" connections between a web browser and the machine. In other words, there is a persistent connection between you and the server, and both sides of the connection can start sending data at any time. The XTM Workbench application uses WebSockets to establish the connection.
