Hi Taj, say you have two tomcat servers that you can access at https://ec2-46-51-148-192.eu-west-1.compute.amazonaws.com:8443 and https://ec2-47-51-148-192.eu-west-1.compute.amazonaws.com:8443 and on both machines you have installed memcached, running on port 11211,
then you can configure msm in both tomcat2 with memcachedNodes="n1:ec2-46-51-148-192.eu-west-1.compute.amazonaws.com:11211,n2:ec2-47-51-148-192.eu-west-1.compute.amazonaws.com:11211" For further questions regarding msm I suggest you ask on the msm mailing list (http://groups.google.com/group/memcached-session-manager/) as this is more specific to msm than to tomcat.
