useDirtyFlag is not used with the DeltaManager, only with the
SimpleTcpReplicationManager.
As the name suggest, the DeltaManager only replicates deltas, and hence it can only
replicate when the session is dirty.
The clustering configuration has changed a little bit since 5.0.19, to make it more
modularized.
Also, the debug flag is a thing of the past, the clustering module is currently using
the commons logger, same way all the other
components are using it.

Subject: Clustering with 5.0.19
Hi,
I've successfully clustered two instances of Tomcat on different machines
and I'm now trying to do some fine tuning on a struts based site.
I want to make sure that the session is only being replicated when it needs
to be. I have useDirtyFlag="true" although I'm not sure that it isn't still
being re-sent after every request. I have the following Cluster element in
my server.xml -
<Cluster
className="org.apache.catalina.cluster.tcp.SimpleTcpCluster"
managerClassName="org.apache.catalina.cluster.session.DeltaManager"
expireSessionsOnShutdown="false"
debug="10"
printToScreen="true"
useDirtyFlag="true">
Although I have the debug/printToScreen attributes, I'm not seeing any debug
information about session replication. How can I get some debug info?
Any help greatly appreciated!
Thanks,
Sam Lawrence
