you to do the following:

  class PostsController < ApplicationController
    use AutheMiddleware, :except => [:index, :show]
  end

Now that we always return a proxy from mb_chars, even in 1.9, all Strings coming back from AS are UTF-8.

If you have existing Metals, you have a few options:
* if your metal behaves like a middleware, add it to the
  middleware stack via config.middleware.use. You can use
  methods on the middleware stack to control exactly where
  it should go
* if it behaves like a Rack endpoint, you can link to it
  in the router. This will result in more optimal routing
  time, and allows you to remove code in your endpoint
  that matches specific URLs in favor of the more powerful
  handling in the router itself.

For the future, you can use ActionController::Metal to get
a very fast controller with the ability to opt-in to specific
controller features without paying the penalty of the full
controller stack.

Since Rails 3 is closer to Rack, the Metal abstraction is
no longer needed.

_helper module included in the view.

- ensures that protect_against_forgery? is present when a helper
  included in a partial that is rendered by the template under test
  calls it (which happens in FormTagHelper#extra_tags_for_form, for
  example).

- decouple tests from the test case class by moving them outside
- split out more TestCase subs as cleaner way of avoiding bleed of
  class level concepts

- enables alternative testing frameworks to include AV::TC::Behavior
  instead of subclassing AV::TC
- also added tests and code for:
  - test view delegates :notice to request.flash
    - useful since generators generate views that use notice
  - test case doesn't try to include modules that are actually
    classes

Add test that shows how link text can contain HTML if needed:
the trick is using block form in combination with `raw`.
Let link text be automatically HTML-escaped
