<p>I am using htaccess in my projec.there is login section i want to show the my account page as <a href="http:///www/domain.com/username" rel="nofollow">http:///www/domain.com/username</a> . But there is a problem because i have also made a cms which is open as <a href="http:///www/domain.com/cms" rel="nofollow">http:///www/domain.com/cms</a> . 
                                        Although i have validate the user name But there is same page open when i open the cms or user profile page.
