Ejb 2.0 Handles for Stateful bean

How EJB 2.0 Object handles (retrieved from getHandle() )help resuming after a disconnect from the server for Stateful Beans ??

In our application architecture, we are keeping the Handle of the stateful bean in a cache at the client side. If the the node in the cluster on which the Stateful bean was created goes down due to some reason, will the handle redirect the next call on the stateful to a new node ?? Is there any configuration that we can do if a Node goes down then reroute the calls on the Stateful Bean to another node in the cluster ??
