Hi Douglas,
Yes you're right, it does. You just cannot do a simple (stateless)
forward for failover, you need to establish a transaction (e. g.
t_relay()) and you need a failure-route handling the error (if there is
any error). And don't forget the flags of the dispatcher (Flag 2 needs
to be enabled).
