Hello,

after cr_route() that sets the RURI set $du (pseudovar .... needs pv.so 
afaik ) to either of the 2 balancers (or to a domain that resolves to 
both of the two balancers - for load balancing). $du will set the 
destination uri of the package without modifying the RURI (which is set 
by cr_route()), so the balancer will route the message to the client.

Cheers
