Because this is Heroku, you cannot use apache or nginx configs. What you can do is put a before_filter in your ApplicationController, assuming you have 3 or more controllers like these below, although of course they will be in separate files

class ApplicationController < ActionController::Base
    def redirect_https        
        redirect_to :protocol => "https://" unless request.ssl?
        return true
    end
    before_filter :redirect_https
end
class TypicalController < ApplicationController
    def blah
    end
end
class HomePageController < ApplicationController
    skip_before_filter :redirect_https
end

You may also need to fiddle your routes a bit when using devise, but I suspect that was just the way we did it so I won't get into those details here, and I've modified the code above to avoid that complication.

happy hacking.
