Subject Re: Horizontal Cluster Session Persistence during Failover
Date Fri, 18 Sep 2009 15:44:29 GMT
I ended up using Option 2, which ended up being very easily to
implement. (http://tomcat.apache.org/tomcat-6.0-doc/config/cluster-interceptor.html)

The network admin had previously assured me that multicast packets
were working properly between the two servers.

Thank you for your help!
