I've been even trying using Squid 3.2.0.2, which I manually compiled. As you know, Squid 3.2.0.2 has better support for HTTP/1.1 (I thought it was something related with that, as Squid 2.6STABLE21 uses HTTP/1.0). Now, with the sniffer I see HTTP/1.1 responses from Live servers through Squid (when with Squid < 3.2 I was getting HTTP/1.0 responses). Furthermore, balance_on_multiple_ip is off by default in 3.2. Nothing changed. I have to use this old software as I have _many_ users with this software already installed, and upgrading would be a pain right now. I don't think the problem is that Live servers are refusing to login old releases. I was able to login in from the same clients using direct connection and through an ISA server 2006 .... :( Thanks!
