Re: svn commit: r980378 - in /tomcat/trunk: java/org/apache/catalina/ha/

webapps/docs/config/
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?

Posted by Keiichi Fujino <kf...@apache.org>.
Sorry.
This rev is just remove defaultMode and add maxActiveSessions.
domainReplication was not related.
I send another proposal mail.
