Force https on a directory

Is it possible to force https on a directory for example if a user tries to access that directory via http it auto redirects to https?

RewriteEngine on
RewriteCond %{HTTPS} off
RewriteCond %{REQUEST_URI} ^/mysecuredirectory/.*$
RewriteRule ^/(.+)$ https://www.mydomain.com/$1 [R]

that works fine
