By "on line" do you mean the FAQ
(http://wiki.squid-cache.org/SquidFaq/ProxyAuthentication#head-1d6e24e071a1a5e65f112d9a96cdf1320684a8f2)?
  If so, did you test the helper as the cache_effective_user? When
prompted for authentication, were you prompted for the Windows domain,
or did you include it?

Hopefully, this is a typo in the email only. I'm not sure how this
misspelling would effect authentication.

This would allow internal_src computers to surf without authenticating.
Perhaps what you are trying to do.

Seeing as you don't have any cache_peers assigned, this is not going to
do what you expect.
