Server to server Communication behind a load balancer

Question

I have two IIS servers sitting behind a load balancer. And my application's DNS is app.domain.com. I should have a way to communicate from one server to other server without touching load balancer. Application in both servers is listening to port 80. Also I have more than one application deployed in same port in these servers. How can I refer to (URL) to individual servers without using DNS.

Answer 1

使用带有HOST标头的IP：port可以区分每个节点中的多个应用程序。
