Is there a specific requirement for session replication? Because you might get 
generally better results if you just use sticky sessions.
That buys you load balancing, but not complete failover - but it may be enough, 
if your failure rate is acceptably low.

I've set up session replication for a couple of clients, and the whole thing 
just seemed a bit fragile to me. I'd prefer to use a database for session 
management in this case, I think - which might involve using Client variables 
instead of Session variables, or might involve custom code to synchronize 
Session variables with a database.

No, there is no specific requirement for session replication. It would just be 
nice to see if that could be sorted out at the same time.
We encounter problems regarding this (clients losing their session) very 
seldom, but if the session replication was working as it should those problems 
would be eliminated also.. :)

Thanks,
Helge
