Yes, we are trying to convince our customer to go on last stable version released for the 4 upstream Squid, and schedule 2.6 migration for 1500 others but we need a good reason (or proof) and it's seems that 3.1 doesn't change anything in our case (I mean, visible change)... or maybe, I didn't see it. Maybe should I try 2.7 instead of 3.1 ? it seems 'act-as-origin' option you told me is not available and could improve the bandwith management. In any cas, thank you very much for your assistance!
