-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA256 Ah - in Squid's wiki don't pay attention on Variant III. This is minimalistic topology, main goal was as minimum hardware units as possible (for cost minimization). Also VRF-variant still in progress. We can't solve DNS proxying task as required yet. 25.10.2016 0:44, Eliezer Croitoru пишет: > Well I do agree on most of the things but it seems that CPU is missing in > some devices and there for a simpler protocol is better but….
