Load balancing for REST in Service Bus

Hello all,

I am researching how to use load balancing in Service Bus. In the sample of load balancing in Service Bus SDK, I see it uses TCP binding. How can we do load balancing using REST? In my situation, I will have many WCF services hosted in different machines that use REST protocol to expose the same URIs, and clients will call via HTTP request to get information from services, the client will send request to Service Bus, then I would like Service Bus will find only one of available services. Can anyone advise me how to do this?

Thanks.
