ruby on rails - Heroku is not including headers with assets -

currently i'm using unicorn server rails_12factor gem in order serve assets rails server. main application url returning right response headers, assets urls homecoming responses without headers (e.g cache-control) , need them proper app functioning.

solved adding

config.static_cache_control = 'public, max-age=1000'

to production.rb.
