I have http://www.example.com/contact-us.php
URL which is working perfectly but if someone put http://www.example.com/contact-us.php/contact-us.php
it shows the page with CSS disturbed.
Can we show page not found message to users for this http://www.example.com/contact-us.php/contact-us.php
URL? If this page is or is not present.
Update :
My .htacess file - /public_html/.htaccess :
RewriteCond %{REQUEST_FILENAME} !-f
RewriteRule ^(.*[^/])$ http://%{HTTP_HOST}/$1/ [L,R=301]
