title: Rails 3.1 Asset Pipeline and Caching
body: <p>I'm working with Rails 3.1's asset pipeline and although it seems to work flawlessly in my development environment on my localhost, I'm having huge issues with it on engine yard.</p>
  
  <p>Here's my basic problem.</p>
  
  <p>When I include images for a background in one of my scss files:</p>
  
  <pre><code>      a {
          color: #3c7f8b;
          font-weight: bold;
          padding-left: 35px;
          font-size: 13px;
          display: block;
          background: white url(shade.png) top right;
          &amp;:hover {
            color: #222222;
            background: white url(shade2.png) top right; }
          &amp;.on {
            color: #222222;
            background: white url(shade2.png) top right; } } }
  </code></pre>
  
  <p>I run into the following issues:  Even though I have precompiled my assets, the browser requests <code>/assets/shade.png</code> instead of <code>/assets/shade-FINGERPRINT.png</code> which is the actual file that exists.</p>
  
  <p>Does anybody know what I can fix this issues with referencing images in my assets folder inside my .scss files?</p>
