Hi.

SimpleTcpCluster#sendClusterDomain called when domainReplication is
true is as follows now.

=3D=3D=3DSimpleTcpCluster#sendClusterDomain=3D=3D=3D
public void sendClusterDomain(ClusterMessage msg) {
    send(msg,null);
}
=3D=3D=3D =3D=3D=3D
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?
