Redirect with htaccess

the url of my site is: http://www.mysite.com/site

and I want that requests as http://www.mysite.com/[ANY_NAME]

are redirected to http://www.mysite.com/site

RewriteEngine on
RewriteCond %{REQUEST_URI} !^/site.* # if its not /site
RewriteRule .* http://www.mysite.com/site [R=301,L]

if 'site' is a directory, you have to add a slash / after 'site'
