ACL random uses the operating system random() number generator. A new random number is selected each time the ACL is checked. The ACL will declare match vs. no-match depending on whether that number is below or above a defined squid.conf threshold value. > Can I make certain the next traffic will go to which Web server? Not using ACL random. For certainty you need one of the many load balancing cache_peer selection algorithms. Which naturally require the server(s) to be cache_peer.
