Session Replication w/ Tomcat 5.0.30

["Jalenak, Jerry" <JJ...@netopia.com>]

I'm testing a clustered Tomcat (5.0.30) configuration on Windows XP
Professional, behind Apache 2.0.54 with mod_jk as my load balancer.
Load balancing works fine, as I can see sessions being dispatched to
each Tomcat from mod_jk (sticky sessions is disabled.)  The problem I
have is that session replication between the Tomcat instances is
failing.  I've verified that the multicast 'heartbeats' are being sent
(via Ethereal), but I never see any TCP traffic between the instances.
This PC is NOT multi-homed (only have one network card), but I've been
able to do similar setups in Linux (multiple instances on one server)
without any problems.

 

Does anyone have a suggestions on what I can try to do to get sessions
to replicate?

 

Thanks!

OK,

a) windows standalone need that mcastBindAddress is set to 127.0.0.1.
b) Please, use for consists sessions handling sticky session at mod:jk, 
backup is only for failover.
c) Used tomcat 5.5.9 with cluster fix pack
