Hey, I have a LB set up in Azure that fronts 2 VMs. There is a health probe that determines "health" status of the backend servers and once the VM is reported as unhealthy, all new connections are routed to the only healthy node.
My problem is that the existing TCP connections are still routed to the same node which could be now unhealthy which creates an interruption in service. I have set IIS app pool Rapid-Fail Protection setting to TcpLevel which should terminate all TCP connections when app pool is shut down. However, existing connections are still routed to the server after app pool is stopped. Is there a way to force new tcp connections to be established in this scenario?
