Consumer-producer in wcf

Is there any example of a consumer-producer type web service written in WCF? What I am trying to do is write a web service where a producer can publish/upl开发者_如何学编程oad variables (in this case, cookies), via a Method, and the consumer will recieve each new published cookie (or can be anything).

Thanks

I think you're looking for callback operations. The consumer can subscribe to receive each generated cookie.
