title: Precompiled CSS not found in Rails 3.1 production mode
body: <p>When I start up rails in production mode, it precompiles all the assets but is unable to serve the application.css asset. I looked in <code>public/assets</code> and the precompiled application.css exists.</p>
  
  <p>However, I get a 404 whenever I try to access it from the page.</p>
  
  <p>These are the instructions I use to launch the server, if that may help at all.</p>
  
  <pre><code>RAILS_ENV=production bundle exec rake assets:clean
  RAILS_ENV=production bundle exec rake assets:precompile
  rails -e production
  </code></pre>
