Hmm.. I'm having a hard time getting it to work.. Here is the configuration
I've got on my ser box.

# subsequent messages will go through our proxy; that's
# particularly good if upstream and downstream entities
# use different transport protocol
record_route();
# loose-route processing
if (loose_route()) {
t_relay();
break;
