The index.html page in the code sample shows how to use the SignalR jQuery library to communicate with a SignalR hub. The code carries out many important tasks. It declares a proxy to reference the hub, declares a function that the server can call to push content to clients, and it starts a connection to send messages to the hub SignalR provides a simple API for creating server-to-client remote procedure calls (RPC) that call JavaScript functions in client browsers (and other client platforms) from server-side .NET code. SignalR also includes API for connection management (for instance, connect and disconnect events), and grouping connections
