How to reset authentication

[weiheon]

Hi WebmasterWorld.com,

WebmasterWorld have previously solved my page redirection based on authentication problem. Here is content of my .htaccess file, there are quite a number of users that will be redirected to their respective directory and below is the example for one of them : -

RewriteEngine on
RewriteCond $1!^tom/
RewriteCond %{REMOTE_USER} ^tom$
RewriteRule (.*) /home/mainsite/tom/$1 [L]

However, I notice that I need to exit my browser and load it again in order to log in again as a different user. Is it possible to trigger the authentication window again when I load www.mainsite.com without exiting the browser? How do I do it?

Regards,
Wei Heon
