Using expire_page on Heroku Cedar?
===

Has anyone managed to use expire_page with Heroku on the Cedar stack? I have a back and forth with support that has been unproductive. From my testing, it works with a single dyno but when you have multiple dynos, only one expires the page. So, it will serve the old page sometimes. I know Varnish was an option in previous stacks but what is the HTTP cache solution for Cedar? Right now I am just using expire_action with memcached but this is not as good because it still hits the Rails stack. 

Thanks in advance.
