ActiveSync - CAS

ferrarista asked
Last Modified: 2016-10-07
I'm not quite sure how ActiveSync works when working with two load balanced CAS servers.
Do they use the same CAS server for a certain lenght of time ? Or do they costantly talk to either server ?

I was doing a test like refreshing my inbox on the mobile device and I can actually see IIS traffic on both CAS servers. So how does it actually work ? I cannot find any material to explain this. Would love to get an insight.

Thanks so much.
