ExpireSession settings

[Greg Dick <gr...@icesoft.com>]

Hi,

We have an application with an HttpSessionListener on Tomcat 6.0.14 with 
an Apache 2.2 load balancer. We have gone through a variety of config 
settings regarding "expireSessionsOnShutdown" and we're a bit confused 
as to what we should be seeing.

When a user hits the site and a new session is created, we see this 
message on both nodes of the cluster. Perfect.

When we shut down the node that has been serving the client, we always 
see a sessionDestroyed message on that node for the client whether we 
have the simple configuration:

<Cluster className="org.apache.catalina.ha.tcp.SimpleTcpCluster" />

or try to add a manager to the configuration:
<Manager className="org.apache.catalina.ha.session.DeltaManager"
                  expireSessionsOnShutdown="false" />

We never see a sessionDestroyed message on the node that isn't shutting 
down. This may be all right, as the session might be duplicated once the 
downed server is restarted, but changing the config to this:

<Manager className="org.apache.catalina.ha.session.DeltaManager"
                  expireSessionsOnShutdown="true" />

doesn't seem to make any difference. Does this setting change the way 
sessions are expired throughout the cluster?
Thanks in advance.
