does it work if you first use the first node, wait for redeployment, and then deploy on the other node (i.e. not using /farm but both /deploy folders?)
Hi, in fact playing with "ScanPeriod" attribute in farm-service.xml solved my problem :
Now when I'm updating something my first node is redeploying quite fast, while my second node is waiting a bit more before updating the webapp. So The second node is able to feed the first node with existing sessions before it restarts itself and loose the sessions.
Thanks for you reply, though
