  # RedirectHelper actually takes advantage of LinkHelper.link_raw to build the links
  # it redirects to.
  # It doesn't do much else than this:
  #     setting a status-code of 303 and a response['Location'] = link
  # returning some nice text for visitors who insist on ignoring those hints :P
  #
  # example of usage:
  #   redirect MainController
  #   redirect MainController, :foo
  #   redirect 'foo/bar'
  #   redirect :index, :status => 309
  #
  # TODO:
  #   - maybe some more options, like a delay
  #
