WAS 6.0.2 and Session Replication

Hi,
I'm currently looking at moving from Websphere Network Deploy 5.1.1 to Websphere Network Deploy 6.0.2. One of the things I need to cover is session replication in a test cluster (two cluster members on same host). I have a war file thats deployed to a cluster with two servers. We log in (war file offers log in) and if one of the servers in the cluster dies then the user should be redirected to the application welcome page (not made to log in again). This works fine in 5.1.1 but I am having alot of trouble with 6.0.2.

WEith 5.1.1 the cluster always directs the requests to the same cluster member only redirecting once that member is killed. With 6.0.2 this is not the case. Some requests go to the memberA and some to memberB. When this happens the user can not get off the application default welcome page. No errors are logged. I really do not know why this works in 5.1.1 and not in 6.0.2, has anybody got any ideas? Key configuration details are:
1 cluster, 2 members on same machine.
I have NOT selected 'Prefer local' for the cluster (I have tried it with this ticked but no difference), not have I selected 'Enable high availability for persistent services'
For my replication domain I have selected the default of a single replica
For each cluster member the replication mode is 'Both client and server' and in Custom Settings I write 'All session attributes'
For the deployed war I have NOT selected 'override session management' though this is selected for 5.1.1.
The Replication domain is the cluster to which the war is deployed and the replication mode is 'Both client and server'

Any help much appreciated,
Thanks,
Aoife
