title: Best way to combine and minify JS / CSS on Heroku
body: <p>First of all, according to <a href="https://stackoverflow.com/questions/1778083/why-does-a-rails-app-on-heroku-serve-assets-via-all-css-and-locally-via-individua/1778139#1778139">this answer</a>, the <code>:cache =&gt; true</code> option on <code>stylesheet_link_tag</code> and <code>javascript_include_tag</code> doesn't work on Heroku. Is this true? I've found <code>:cache =&gt; true</code> to work occasionally, but not always (weird!)</p>
  
  <p>Also, what's the best solution here? Ideally it would seamlessly combine and minify all CSS / JS. <a href="http://github.com/amasses/heroku_asset_packager" rel="nofollow noreferrer">Heroku Asset Packager</a> claims to do this -- are there better options?</p>
