What is the most efficient way to stream values to clients in c#

Question

I'm wondering how websites like http://www.eztrader.com/Trading.aspx stream prices to users. I know I could set an ajax call with a timeout to request the price from the server every 2 or 3 seconds, but is there a more efficient way of doing this? I'm using .net mvc 4.0 on the back-end.

Answer 1

You can try SignalR. It's a .NET library designed for this kind of real-time functionality.
