Session replication in tomcat5
All,
I'm wondering what it really means that the <Cluster/> element is nested
inside a <Host/> element?
Our servers are load balanced on network layer level, without any software
interaction, so actually all of the tomcat instances are running separately
without using the built-in load balancing. But since the web servers are
using virtual hosting I need to place several <Host/> elements into the
server.xml to let all the individual sites have their own environment.
In a scenario like this how I can do the session replication? If I place it
in one of the <Host/> elements then sessions only for that host will be
replicated? How I need to configure the tomcat instances to have all the
sessions for all of the (virtual) hosts replicated?
Can anyone shed light on this please?
Thanks,
gergoe

yes, especially mcast address, that essentially is what defines a group of members

Thanks, it sounds promising (just need to survive 'till that time ;-)
Anyway, is there anything I need to know or be aware of when I configure
many clusters between two tomcats? Should the (mcast and the tcp) ports be
different for each of them?
Thanks,

it is currently one of the draw backs that the cluster element is inside the a host, cause in your scenario you would need to
configure several clusters, one for each host.
I'm currently slammed with work, but we started doing some serious refatoring for the Tomcat 5.1 version and this is a strong
candidate
