What are you referring to when you say "authentication" because > the knee-jerk reaction is to assume a username and password is > authenticating... Yes there is a user/pass. Everyone is saying that the broswer shouldn't indiscriminately provide crednetials, which I agree with. However, in the setup I am proposing, the browser isn't submitting credentials. The traffic is intercepted by a local proxy, which does *not* have authentication and only responds to localhost traffic. The local proxy then queries the parent cache with the u/p provided by the login parameter in the cache_peer config option. So the authentication is there, it just doesn't require any user interaction.
