Hi all,
I've got wicket 1.4-m2 based application running on two different network
hosts configured as Tomcat 6 Simple TCP cluster.
I try to simulate failover with session replication using the following
schema:
1) Log into the first server, store some info in HTTP session
2) Access mounted page on the first server, i.e.
http://first.server/mounted/page
3) Try to access the same page on the second server, i.e.
http://second.server/mounted/page
I assume that HTTP session should replicate between Tomcat's and I want to
get immediate reply from the second server, but all I get is forwarding me
to the login screen and the following entries in log:
Jun 25, 2008 5:10:39 PM org.apache.catalina.ha.session.DeltaManager
