Hi,
Id just configure a tomcats cluster with two nodes. The version of Tomcat is 6.0.24 with JRE 6.0.15 on Ubuntu 9.10. Clusters part of my Server.xml: <Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" channelSendOptions="8"> <Manager className="org.apache.catalina.ha.session.DeltaManager" expireSessionsOnShutdown="false" notifyListenersOnReplication="true"/> <Channel className="org.apache.catalina.tribes.group.GroupChannel"> <Membership className="org.apache.catalina.tribes.membership.McastService" address="228.0.0.4" port="45564" frequency="500" dropTime="3000"/> <Receiver className="org.apache.catalina.tribes.transport.nio.NioReceiver" address="192.168.1.108" port="4000" autoBind="100" selectorTimeout="5000" maxThreads="6"/> <Sender className="org.apache.catalina.tribes.transport.ReplicationTransmitter"> <Transport className="org.apache.catalina.tribes.transport.nio.PooledParallelSender"/> </Sender> <Interceptor className="org.apache.catalina.tribes.group.interceptors.TcpFailureDetector" /> <Interceptor className="org.apache.catalina.tribes.group.interceptors.MessageDispatch15In terceptor"/> </Channel> <Valve className="org.apache.catalina.ha.tcp.ReplicationValve" filter=".*index.*;"/> <Valve className="org.apache.catalina.ha.session.JvmRouteBinderValve"/> <Deployer className="org.apache.catalina.ha.deploy.FarmWarDeployer" tempDir="/tmp/war-temp/" deployDir="/tmp/war-deploy/" watchDir="/tmp/war-listen/" watchEnabled="false"/> <ClusterListener className="org.apache.catalina.ha.session.JvmRouteSessionIDBinderListener"/> <ClusterListener className="org.apache.catalina.ha.session.ClusterSessionListener"/> </Cluster> Clustering connection work well and I see members appear or disappear in the log file. Log node 1: INFO: Created a buffer pool with max size:104857600 bytes of type:org.apache.catalina.tribes.io.BufferPool15Impl 25 févr. 2010 14:35:42 org.apache.catalina.ha.tcp.SimpleTcpCluster memberAdded INFO: Replication member added:org.apache.catalina.tribes.membership.MemberImpl[tcp://{192, 168, 1, 108}:4000,{192, 168, 1, 108},4000, alive=1019,id={93 73 -36 -95 -25 79 67 32 -89 30 -119 95 -9 24 87 -24 }, payload={}, command={}, domain={}, ] Log node 2: INFO: Starting clustering manager at /SessionListener 25 févr. 2010 14:35:45 org.apache.catalina.ha.session.DeltaManager getAllClusterSessions ATTENTION: Manager [/SessionListener], requesting session state from org.apache.catalina.tribes.membership.MemberImpl[tcp://{192, 168, 1, 115}:4000,{192, 168, 1, 115},4000, alive=57336,id={35 -70 -95 77 106 -12 71 31 -111 47 -36 105 30 78 -58 60 }, payload={}, command={}, domain={}, ].

Id just have any questions regarding filter of replication valve. The filter receive java regular expressions and keep out all object corresponding with filter, Can I use expression ^[.*specific_folder.*]; as filter for limited the replication of data to a little part of application where was deployed in a specific folder ? And when object must be keep out, send tomcat a replicated session empty or dont send a session ? Thank you for your work, its very precious for noob like me :-)
