  www.domain.fr  => /home/example/vhosts/domain.com/public_html
  www.domain.de  => /home/example/vhosts/domain.com/public_html

Option B - Sub domains

  en.domain.com => /home/example/vhosts/domain.com/public_html
  fr.domain.com => /home/example/vhosts/domain.com/public_html
  de.domain.com => /home/example/vhosts/domain.com/public_html

Options C - Mixed domains

  www.domain.com => /home/example/vhosts/domain.com/public_html
