Subject Re: Tomcat 6.0 vs Tomcat 5.5 Clustering Changes
Date Thu, 04 Jan 2007 15:33:14 GMT
Mainly its been refactored, farming as in 5.5 is still pretty broken and 
hasn't been worked on.
What has been worked on is the separation of session replication vs 
cluster/group communication. These are two separate packages now
o.a.catalina.tribes (group com, simple overview at 
http://people.apache.org/~fhanik/tribes/docs/introduction.html)
o.a.catalina.ha (data replication)

The cluster config has been documented in the reference, in 5.x it wasn't.
Some new features added (but not limited to)
1. primary/backup replication using shadow maps
2. context attribute replication
3. Ability to use per context managers when clustering contexts, ie, one 
can use a BackupManager and the other a DeltaManager
and so on, to get the documentation up to date is still on the todo list
