basic www auth

[Crist�v�o Dalla Costa]

Hi

I'd like to do basic www authentication on my scripts. Apache::Auth::DBI 
isn't good since it would waste a database connection, and just add 
unnecessary complication. I'd like to do something like:

if (! check ($username, $password)) {
        send_unauthorized_http_headers ();
}

I guess I can send the 401 response using $r->header_out, but I still 
haven't found out how to get the authentication information: username 
and password.

Thanks in advance.
