Communication between multiple web applications using SignalR

Question

I have two different web applications that need to communicate with each others (which I can currently accomplish by using Silverlight Duplex but that doesn't scale very well). After reading about SignalR, I'd like to give this a try but failed to find much documentation on how to do this. Any advice on ho to get started would be greatly appreciated.

Thanks!

More specific Info: Example: Application A (Bidding Interface) - A web page to allow multiple end-users to place bids on certain items.

Application B (Managing Interface) - A web page to allow a user (or could potentially be multiple users) to monitor/control the actions from Bidding Interface.

So when a user from Application A place a bid on a piece, I'll need a way to alert Application B that a bid has been placed. Then from Application B, should the user choose to accept the bid, I need to send an alert back to Application A (to update current price, increase bid etc...)

Answer 1

In all honesty, in might just be simpler to have each application push the notifications to each other via standard service calls (WCF, ASMX, HTTP handler endpoints, MVC controllers, whatever). SignalR is useful in browser to server communications because there isn't a consistent way to do push from the server to a connected browser. But from web app to web app pushing is simple; Application A just calls a service endpoint on Application B to notify it of something happening.
