Rails 3 SSL Deprecation

I am upgrading an application to Rails 3.0.0 and am wondering if the standard method for adding SSL has changed (I vaguely remember demos indicating the router could now handle SSL, though I'm not sure if it was just for demonstration purposes). I currently use the "ssl_requirement" gem, however it gives:

DEPRECATION WARNING: Using #request_uri is deprecated. Use fullpath instead. (called from ensure_proper_protocol at /Library/Ruby/Gems/1.8/gems/ssl_requirement-0.1.0/lib/ssl_requirement.rb:53)

Also, it appears to break when handling the new 'data-method' attributes. For example:

<%= link_to "Logout", user_path, :method => :delete %>

Works fine when accessing from an SSL section of the application, but fails (attempts to render show action) when followed from a non-SSL section (all actions in the user controller require SSL, although I understand that the destroy action does not transmit secure data).

After spending an afternoon looking for the best solution I settled on the approach described in this article: http://clearcove.ca/blog/2010/11/how-to-secure-a-rails-app-on-heroku-with-ssl-firesheep/ which referenced this article: Force SSL using ssl_requirement in Rails 2 app

Basically do this:

# lib/middleware/force_ssl.rb
class ForceSSL
  def initialize(app)
    @app = app
  end

  def call(env)
    if env['HTTPS'] == 'on' || env['HTTP_X_FORWARDED_PROTO'] == 'https'
      @app.call(env)
    else
      req = Rack::Request.new(env)
      [301, { "Location" => req.url.gsub(/^http:/, "https:") }, []]
    end
  end
end

# config/application.rb
config.autoload_paths += %W( #{ config.root }/lib/middleware )

# config/environments/production.rb
config.middleware.use "ForceSSL"
