sessions on tomcat restart in cluster

[Tsirkin Evgeny]

Hi all!
Does the cluster DeltaManager supports storing the session in a file on
restarts?
It seems to me that when closing both servers in my cluster and then
starting them again
the sessions are not restored .What is a solution for that .
(P.S. tomcat 6.0 & apache 2)
Thanks
EVgeny
