Description:
------------
The URLs such as 
http://www.php.net/manual/en/function.date.php that have "www" in them does not work.  It requires signing into the php.net site as the browser says "http://www.php.net is requesting your username and password. The site says: “Restricted Content”".

The URLs such as http://php.net/manual/en/function.date.php that do not have "www" in them works fine.

Expected result:
----------------
The appropriate manual page must appear.

Actual result:
--------------
A dialog with username and password appears.  When you cancel the dialog, the following error appears.
