Hello,
Yes! There is one very magic line in your code, which solved my problem. It is
this line:
$r->err_headers_out->set("WWW-Authenticate" => 'Basic realm="My Site"’);
I always used:
$r->headers_out->set("WWW-Authenticate" => 'Basic realm="My Site"’);
When digging into the documentation one can read: "The difference between
headers_out and err_headers_out, is that the latter are printed even on error,
and persist across internal redirects (so the headers printed for ErrorDocument
handlers will have them).”
When using Apache 2.2 with mod_perl 2.0.6 using “headers_out” was enough. When
using Apache 2.4 with mod_perl 2.0.9 seems to be more correct. :-)
Thank you!!!
