I recently discovered SignalR, seems that it can fit into high-load projects with hundreds of concurrent connections.
But as far as I can see, it is only supports full communication type of software (real-time).
So here is the question: is it possible to create REST services with SignalR without client code & persistent connections?
Basically I just need that asynchronous high performance server side part from SignalR & HTTP request handler (if exists).
Regards.
Nope that's not SignalR's purpose, use WebApi if you want to make a streaming restful api. Take a look at push content http://blogs.msdn.com/b/henrikn/archive/2012/04/23/using-cookies-with-asp-net-web-api.aspx.
