title: I'm getting `GET http://localhost:4567/my_app.dart.js 404 (Not Found) ` in Chrome, but works fine in Dartium
body: <p>I'm trying to get my dummy Dart webapp running in browsers. Here's the code of my html page:</p>
  
  <pre class="lang-html prettyprint-override"><code>&lt;!DOCTYPE html&gt;
  &lt;html&gt;
    &lt;head&gt;
      &lt;meta charset='utf-8'&gt;
      &lt;!-- Always force latest IE rendering engine or request Chrome Frame --&gt;
      &lt;meta content='IE=edge,chrome=1' http-equiv='X-UA-Compatible'&gt;
    &lt;/head&gt;
    &lt;body&gt;
      &lt;div id='button'&gt;hello world&lt;/div&gt;
    &lt;/body&gt;
    &lt;script src='my_app.dart' type='application/dart'&gt;&lt;/script&gt;
    &lt;script src='packages/browser/dart.js'&gt;&lt;/script&gt;
  &lt;/html&gt;
  </code></pre>
  
  <p>and this is what I'm getting in js console when trying to open it:</p>
  
  <pre><code>GET http://localhost:4567/my_app.dart.js 404 (Not Found) 
  </code></pre>
  
  <p>(I'm running it on a local server, thus the url - got the same error if simply opening an html file though).</p>
  
  <p>If I open the same url in Dartium, the webapp works. So the problem, I suppose, is that <code>dart.js</code> doesn't work as expected. What could be the problem?</p>
