IIS - re-route request to another node

Question

I have deployed application on two windows servers(nodes) using IIS (7+). Under default web site I have configured two different services/application as follows.

On Node1 I want to stop Service1 & on node2 I want to stop Service2.

Hence, I have created app pool per service & stopped respective service.

Node1::

Service1 -> AppPool1 -> AppPool1 is stopped

Service2 -> AppPool2 -> AppPool2 is running

And vice versa for Node2.

Windows server nodes are configured in round robin load balancer. And accesssible over LB URL "https://LBDomainEntry/". I do access services using below format:

• https://LBDomainEntry/Service1
• https://LBDomainEntry/Service2

Problem: I am getting intermittent issue for web service. Sometimes reuest gets successful sometimes it fails.

Limitations: I don't have control over LB. But I have control on windows servers.

Question:

1. How I can resolve this issue, is there any re-route option available to config in IIS to route it to another node ?
2. I came across ARR (Application request routing) feature, can I use it here & how ?
