running rails app on heroku, can't see static pages in /public folder

I have a couple static pages which when running locally work as localhost:3000/foo.html, but this doesn't work once uploaded to heroku. I tried adding the following to the routes.rb file: match '/foo', :to => redirect('/public/foo.html') but that doesn't seem to work, it redirects me to foobar.com/public/foo.html, but still finds nothing there.
