When using RESTful routes

I had issues using expire_page with RESTful controllers when expiring anything other than the index action because I was basing my expire_page calls off this example.

The solution is to use my_resource_path for example when User with id 5 is updated, you would have to do:

expire_page user_path(user) # or
expire_page formatted_user_path(user, :xml)

This may apply to early versions but I have only tested on v2.1.0

expire_page
