Get the user locale from http headers

If you want to provide default localization support for guest user in your website yo can locate their browser locale by the following code:

def extract_locale_from_header
    unless request.env['HTTP_ACCEPT_LANGUAGE'].nil?
      return request.env['HTTP_ACCEPT_LANGUAGE'].scan(/^[a-z]{2}/).first

This way you can determine on server side the locale of the user currently entered your site.
