Not entirely. Radiant sets up the values for cache control: http://github.com/radiant/radiant/blob/master/app/controllers/site_controller.rb#L7 http://github.com/radiant/radiant/blob/master/app/controllers/site_controller.rb#L46-L53 So we do have control over it. > > If so, does that mean that trying to do what I want to do is basically a > lost cause if I stick with Rack::Cache?

That could be an option too, but might be more work than a new piece of middleware.
