The canvas page name is not an url. It's juste a name.
As I told you before, for your app, it's :

	canvas_page_name: stem_survey


>>>       format.fbml { redirect_to('http://apps.facebook.com/stem_survey/survey_responses/'+@survey_response.id.to_s) 
>>>  }
>>

Here is an example :

	# in config/root.rb
	map.resources :messages

	# in script/console
	>> app.messages_url()
	=> "http://www.example.com/messages"
	>> app.messages_url(:canvas => true)
	=> "http://apps.new.facebook.com/alisterapptrois/messages"
	>> @message = Message.find(:first)
	=> #<Message id: 29, user_id: 1278968509, body: "coucou les gens",  
page_uid: 26149797103, created_at: "2008-10-16 13:59:04", updated_at:  
"2008-10-16 13:59:04">
	>> app.message_url(@message, :canvas => true)
	=> "http://apps.new.facebook.com/canvas_page_name/messages/29"
	>> app.message_url(@message, :canvas => false)
	=> "http://www.example.com/messages/29"
	>> app.message_url(@message)
	=> "http://www.example.com/messages/29"

	# in app/controller/hello_controller
	def foo
		@message = Message.find(:first)
		redirect_to( message_url(@message, :canvas => true))
	end

	# in script/server (logs after calling http://localhost:3000/hello/toto)
