Hi,
I have implemented a JvmRouteBinderValve that detect a session failover.
This valve rewrite the interal session id and send the change to
other backup nodes.
<Cluster ....>
<Valve
className="org.apache.catalina.cluster.tcp.ReplicationValve"
filter=".*\.gif;.*
\.js;.*\.css;.*\.png;.*\.jpeg;.*\.jpg;.*\.htm;.*\.html;.*\.txt;"
primaryIndicator="true" />
<Valve
className="org.apache.catalina.cluster.session.JvmRouteBinderValve"
enabled="true" />
<ClusterListener
className="org.apache.catalina.cluster.session.ClusterSessionListener" /
>
<ClusterListener
className="org.apache.catalina.cluster.session.JvmRouteSessionIDBinderLi
stener" />
</Cluster>
Valve is registered as JMX-MBean and this feature can be disabled by
runtime.
regards
Peter

I don't know if that's a good idea. It looks a bit risky. I think
it should include && (getContext() != null) && getContext
().getCookies().

Also if I remember correctly, session replication with delta
manager (default) applies replica messages to sessions with the
same id: So in a three node cluster with one node failing renaming
the id on a second node might break replication from the second to
the third. Unfortunately I can't check right now, but since it
might be, that 5.5.21 is not too far, I would find this new
rewriting behaviour a bit risky as a default.
I'm also asking Peter about the state of his rewriting listeners,
because I somehow remember a functionality like that might already
exist.
Maybe Filip likes to comment on my first concern.

Rainer
