Hey
everybody,
I would like to configure Tomcat for both session replication

persistence
lags several seconds which is why I don't think that I can simply
replicate sessions over many servers using the database.
I can get the sessions to persist to the database using
org.apache.catalina.session.PersistentManager, and I can get session to
replicate in memory using
org.apache.catalina.cluster.session.DeltaManager, but how to I use both
at the same time?
Here is server.xml with the in-memory replication that works:
