What can work is to add them with a weight of zero first. They won't be elected by the load balancing algorithm but will accept persistant connections based on cookies and/or stick-tables. But if your application is really stateless, maybe it's not worth bothering with this. If a client is switched to another haproxy wihch does not know the server's ID, it will simply be rebalanced, be assigned a valid ID and will stick to this ID on other peers. I don't know if this is an acceptable scenario however. Regards, Willy
