About Content Events Mass-Transit and Stefan Olsens solution I am a little bit lost.

I wish to end up with the solution that Master-server (with the CMS UI) tells the Slaves to flush or update cache whenever there is a content change.

Is all I have to do is to apply Content Events Mass-Transit but using Stefans Event Provider (UdpMulticastEventProvider) instead?

Thanks in advance.

No you don't. you need just one of them - they are all event providers - each utilizing a different underlying mechanism for message transport

Thanks; whats the best way to test if events are being sent and recieved?

Simplest way to test is to edit a content in one instance and view it on another instance. the change should be seen (i.e. cache invalidation messages were sent through)

Understood, and how would I go about to finding out why, if that is not the case?

@quan So applying Stefan Olsens solution and setting up the IP and ports is all I would have to do to ?

There are two settings you need to do

setup Optimizely to use your (custom) event provider
setup your custom event provider so it can send and receive messages over network

I'm not quite sure about (2), but if that's what in the documentation, yes.

I ended up using Stefan Olsens solution with UdpMulticastEventProvider and configured the Host and Endpoints for each specific server (one authoring and two frontservers).

Then had to make sure that the port using UDP trafic was open between the three servers. (Rather OUT from Authoring and IN to frontservers).

After that it worked great.

Big shout-out for Stefan!
