* 3 Antivirus PROXY-PARENT parents of 1.
                                     ^^^^^
                                    of 1 what?

Do I understand if I say that every SP can connect to each of the three PP?

My question is located on the SQUID parent definition. I want that each
SQUID loadbalance incoming traffic to parent pool. My setup must work with

Incoming from where? Client-side?

I would like to know if it is possible to make a connection persistent from
a specific client to a specific parent ? Is it possible to stick traffic
from a client to the same parent (without round-robin algo replay for all
GET query comming from the same client) ?

Going over the SP(i) first? What does the network scheme look like (IP-addressing)?

Can someone give me some lighting points on that kind of setup ?

This looks pretty tough at first sight (since I don't understand what you like to do). Cheers,

Roberto Nibali, ratz
