I have a problem with Session replication. I am running multible tomcat 
instance on the same server. And I have 4 servers of the same configuration 
(Multible tomcat instances). I have enabled the session replication on these 4 
servers (In each instance with different port).


The problem is that All instances see each other. while I only need similar 
instances to see each other.

I'm not sure I understand what you are trying to achieve, what do youmean by "similar"
