Basic Authentication x IIS 5.0 - User and password box appears once time !

We have a main page with a link to a secondary page. We'll call this secondary page as 'www-aaa' is configured with the
option 'basic autentication' in 'directory security', for this way a domain's user and password is required. In www-aaa We have a button 'exit' that close the www-aaa returning to the main page

The problem is that when We click again in the main page in the link www-aaa link, the www-aaa page opens and that domain's user and passoword is not required more. We need that User and password box appears every time that user click on the www-aaa link

We'd like to avoid this problem. And the users are asking me about a Microsoft source for this kind of beahiviour

and read the first bullet point in the "notes" section at the bottom of the
page. Most other browsers have the same behaviour. You need to close all the
browser windows in the current iexplorer.exe process for IE to "forget" the
user's credentials.
