The code below appears to show the text "HELLO WORLD" just fine in Firefox, IE, Safari, but not in Chrome.
<Files wp-login.php>
AuthType basic
AuthName "HELLO WORLD"
AuthBasicProvider file
AuthUserFile /home/.htpasswd
Require valid-user
</Files>
ErrorDocument 401 "Authentication required"
How can I make sure AuthName works in all browsers?
