Hi, I saw this comment in squid.conf for cache_peer directive: use 'weight=n' to affect the selection of a peer during any weighted peer-selection mechanisms. The weight must be an integer; default is 1, larger weights are favored more. so, what's "weighted peer-selection mechanisms"? Thanks. Regards. Enjoy a better web experience.
