Authentication handlers

[Kiran Kumar.M]

hi ,
i'm using mod_perl authentication handler, where 
the user's credentials are checked against a database  and in the database 
i have a flag which tells the login status (y|n),  but aftr the user logs out 
the status is changed to n , my problem is that after logging out if the 
user  goes one page back and submits the browser sends the username and 
password again , and the status is changed to y . Is there any means of removing 
the username and password from the browsers cache.
 
Thanks in advance
