Hi Oliver,
I real tried hard to enable a ClusterCacheRefreshing with 2 full caching 
slides. And can't get it working. This is what I found out:
- If one use udp="false" for every refreshing action a new thread is 
started a the sender and the receiver of the refresh-message. One is the 
NotifyMethod, that is waiting for an answer and the other is the 
NotificationListener that wait for an additional message line. (A bug? )
- Using udp="true" the last started slide receives 
ClusterCacheRefreshing-Notifications but is not able to send them.
- Receiving a ClusterCacheRefreshing-Notifications slide dumps "INFO - 
Resetting cache for ..." for the structure- and contentSubscriber. In 
the debugger I saw that TxLRUObjectCache.remove() is called, but the 
cache wasn't really cleared.
Is it possible to work out two Domain.xml that cluster two slides 
working on one filestore? (Building two workers in a loadbalanced mod_jk 
environment.)
Here are my first suggestions:
		<listener classname="org.apache.slide.cluster.ClusterCacheRefresher">
		<configuration>
			<node local-host="tomcat1"
			      local-port="4410"
			      repository-domain="/"
			      repository-host="tomcat2"
			      repository-port="8080"
		              username="root"
			      password="****"
			      udp="false"
			      />
		</configuration>
		</listener>
