Load balancer Redirection

[Racheal200]

HI ,

We have configured standard load balancer to distribute traffic to VMs in backend pool.

When one of the VM is unhealthy users who are in that VM will be redirected to the other healthy VM but always end up in session expired page.  so the progress is lost . How can we handle this issue? 

Does session persistence : clientIP needs to be changed to None . hope that will not address this issue.

Could some one help on this?

May refer below to inbound connectivity and limitation to fine tune:

@kidd_lp , thanks for the response . But idle timeout is already 15min and health probe pooling intr
eval is every 10sec . There is a lag of 1 or 2 probes every 15min or 30min
