RewriteEngine ON
RewriteRule ^/.+ / [L,R]

That will redirect everything to / as a permanent redirect. Look at http://httpd.apache.org/docs/2.0/mod/mod_rewrite.html for more information on the flags you can add for transparency etc etc.

If you want this in .htaccess make sure you have the correct override directives in your <VirtualHost > config.

If you want to only redirect if there files and directories don't exists already, then this will work:

RewriteEngine ON
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^/.+ / [R,L]

If you never want to have sub-content accessible then remove the condition rules

RewriteEngine ON
RewriteRule ^/.+ / [R,L]
