RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^(.*)$ /folder_name/$1
RewriteCond %{HTTP_HOST} ^(www.)?example.com$
RewriteRule ^(/)?$ folder_name/index.html [L]

RewriteRule !^subdir/ /subdir%{REQUEST_URI} [L,NC]

This will prefix every request for domain2.com with /subdir if it is not already there.
