# Rack::Middleware that returns the number of models in the database for any call to a URL like modelname/count.
#
# Examples:
#   /users/count
#     => returns User.count in plain text
#
#  /articles/1/comments/count.xml
#    => returns Comment.count as XML, e.g.
#       <comments type="integer">5</comments>
#       Note: this does not return Articles.find(1).comments.count like it maybe should!

  # RefererControl is a Rack middleware app which restricts access to paths
  # based on the Referer header. Using RefererControl you can make sure
  # users follow the intended flow of a website. If a controlled path is
  # visited with an unacceptable Referer URI, then a simple 307 Redirect
  # response is returned.
  #
  # RefererControl should also make Cross Site Request Forgery (CSRF) a
  # little more difficult to exploit; but not impossible using JavaScript.
