Hi.
SimpleTcpCluster#sendClusterDomain called when domainReplication is
true is as follows now.
===SimpleTcpCluster#sendClusterDomain===
public void sendClusterDomain(ClusterMessage msg) {
send(msg,null);
}
=== ===
the msg is transmitted to all cluster members.
domainReplication does not work correctly.
Tomcat7 and Tomcat6 have
org.apache.catalina.tribes.group.interceptors.DomainFilterInterceptor.
If DomainFilterInterceptor is used, session can be sent only to the
same domain.
Is DomainFilterInterceptor used instead of domainReplication?
