        Thanks a lot for your answer but I don't understand.

        RR is enough for my usage even if I would prefer a real random algorithm.

        To write my config, I have followed this howto:

        I _want_ to use destination IP selection to force squid to use four
different outgoing addresses. 192.168.1.72 receives a request that it
sends to one of the slave (192.168.7[3456]). First step works fine, but
I don't understand why outgoing address is always 192.168.1.73.
