title: Why does a rails app on heroku serve assets via all.css and locally via individual files
body: <p>I'm a rails newbie, I've been trying to figure out what is going on with the stylesheets_link_tag on heroku.</p>
  
  <p>If I use</p>
  
  <pre><code>= stylesheet_link_tag "style", :cache =&gt; true
  </code></pre>
  
  <p>heroku uses "all.css" and does not pick up the stylesheet, but if I use </p>
  
  <pre><code>= stylesheet_link_tag "style", :cache =&gt; false
  </code></pre>
  
  <p>it serves the stylesheet using its name "style.css". Why?</p>
