What I mean is when I configure the failover between primary and backup
node using piranha, it is doing failover only. The primary or the backup
(when primary is fail) node didn't do the load balancing to the 2 real
servers. Is there any ways that I want to have failover between the
primary and backup node, and at the same time, when requests come in,
load balancing is functioning. (The primary or the backup will load
balance the requests to the real servers)



Thank you
