First of all, according to this answer, the :cache => true option on stylesheet_link_tag and javascript_include_tag doesn\'t work o
:cache => true
stylesheet_link_tag
javascript_include_tag
I haven't tried it on heroku yet, but Sprockets might be good for that. Also, in the past, I've had more luck with
:cache => 'all.css' :cache => 'all.js'
instead of 'true'
