In general, how does it work under the hood? if you have server A and B, using ISynchronizedObjectInstanceCache.Remove on B, how does A get knowledge of that? UDP, Database?
Remove events over TCP (or UDP, you can config) afaik :)
Yep, confirmed! "Changes made using the ISynchronizedObjectInstanceCache interface are synchronized between servers using events in load balanced environments."
If you are using load-balancing set up, then yes it uses UDP to broadcast the "messages"
I'm not sure about the mirroring scenario thoughts ...
