Expand please. The user should get 407 in most events related to
authentication I think.

Reminds me of an old ACL hack I did, changing the semantics of when to
request user credentials. Instead of having them requested by the
proxy_auth ACL, I had them requested if the request was denied and a
proxy_auth ACL had been touched.

Worked quite nicely, making proxy_auth behave more like the other ACL's
in the sense that if the user isn't logged in then the ACL does not
match. However, the change was never pushed forward as it makes it even
harder to configure http_access security properly..

Example of configurations where it is useful:

acl special_users proxy_auth user1 user2 user3
http_access special_sites

http_access allow special_users special_sites
http_access deny special_sites
http_access allow auth

causes any other user who try to access special_sites to be requested
for new credentials..
