.htaccess redirect based on user role

I’m trying to redirect certain users without the correct role to the login page. Currently I’ve gotten it to work with basic “wordpress_logged_in” from the cookie:

RewriteCond %{REQUEST_URI} ^.*staging/.*
RewriteCond %{HTTP_COOKIE} !^.*wordpress_logged_in.*$ [NC]
RewriteRule . /wp-login.php?redirect_to=%{REQUEST_URI} [R,L]

I would like to find the current user’s role, so I can filter based on this role. Is this possible? Thanks!
