##### SUMMARY
<!-- Explain the problem/feature briefly -->
We have Many AutoscaleGroups, and a good portion of them require Source
Based Sticky Session.
In this scenario, the SourceBased does not work:
- Create Autoscale Group, with multiple VMs, and no Sticky Session
- Ensure Autoscale Group is still enabled, and VMs are running.
- Disable Autoscale Group (but do not delete VMs)
- Change Load Balance Rule Sticky Session to -> Sourcebased
- Turn on Autoscale Group
The result, is that the SourceBased Sticky Session does not work.
For us, to overcome the issue, we had to:
- Disable Autoscale Group
- Delete All VMs (Results in downtime)
- Enable Autoscale Group and let is recreate all the VMs
Only then, the SourceBased StickySession works.
