Firstly. Why the complexity with IPs?

  http_access deny !ncsa_users
  http_access allow ncsa_users

Also check that the /etc/squid/squid-passwd has the right user/pass
details inside. It should be created in the format NCSA uses.

  NP: Squid may need to be reconfigured (squid -k reconfigure) for the
helper to pick up changes in this password file.

"Why for love of the Internet? why!!!?" /sigh.

Try and get it working without this violation of HTTP standards killing
potentially useful information.

The above http_access lines are what we consider to be the basic safety
net for HTTP.

Please move your custom login http_access below them. Right now anyone
who can login has unlimited access to do anything nasty to your network
and the rest of the Internet both.

> http_access allow localhost

Stick your alterations to http_access in right here.

An open ICP port. Yay, anyone can cache scan you for content :)

> http_port 3128

Open port 3128 and 8888 ? why not just one?

You want to remove those QUERY bits.

Strange to be allowing Microsoft WebDAV requests through, but stripping
the headers they require to work... oh well.
