Hello! I had the same problem and I did the same thing you are thinking about. I bypassed authentication for java stuff. I've read many things including the sun knowledge base and there are many issues regarding authentication with the jvm, especially with ntlm! You can solve this by creating an acl like this: acl java_jvm browser Java/1.4 Java/1.5 http_access allow java_jvm Remember to keep it in front of any http_access lines regarding authentication, otherwise it won't work. I haven't worked out the windows update issue since I only do it in my servers and when I do I make a NAT rule in my firewall, but I think it has something to do with 443 port (ssl).
