[development] htaccess help

I have a Drupal site installed at /bv, so home page is www.mysite.com/bv I want to be sure when anyone tries www.mysite.com/anypage, they get redirected to www.mysite.com/bv/anypage Is this possible via htaccess? I currently have this rewrite to be sure the www is included (needed for SSL): RewriteCond %{HTTP_HOST} ^mysite\.com$ [NC] RewriteRule ^(.*)$ http://www. mysite.com/bv/$1 [L,R=301] Thanks for any help.
