[Users] Openser 1.1 and Dispatacher Failover

[Carsten Bock]

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).
