title: Requirejs data-main is not setting the baseUrl
body: <p>I set the data-main for Requirejs and according to the documentation that should set the baseUrl for all my script files.  But this is not the case.
  My folder structure is this:</p>
  
  <pre><code>Home/Index.html
  Content/scripts/main.js
  Content/scripts/libs/require/require.js
  Content/scripts/libs/jquery/require_jquery.js
  Content/scripts/libs/jquery/jquery-1.7.1.mins.js
  </code></pre>
  
  <p>Here is the script tag in my <strong>Index.html</strong>:</p>
  
  <pre><code>&lt;script data-main="/PAWS/Content/scripts/main.js" src="/PAWS/Content/scripts/libs/require/require.js" type="text/javascript"&gt;&lt;/script&gt;
  </code></pre>
  
  <p>I would assume it would set my baseUrl to /PAWS/Content/scripts/ but its not working for me. In my <strong>main.js</strong> I do this:</p>
  
  <pre><code>require(
      { paths: 
          {   jquery: 'libs/jquery',
              knockout: 'libs/knockout'
          }
      },
  
      ['jquery/require_jquery'],
  
  
      function ($) { .... }
  );
  </code></pre>
  
  <p>In my <strong>require_jquery.js</strong> file I do this:</p>
  
  <pre><code>define(["libs/jquery/jquery-1.7.1.min.js"], function () {
      return jQuery;
  });
  </code></pre>
  
  <p>But I get a 404 error saying that:</p>
  
  <pre><code>GET http://localhost/PAWS/Home/libs/jquery/jquery-1.7.1.min.js 404 NOT FOUND
  </code></pre>
  
  <p>You see.. my baseUrl should be /PAWS/Content/scripts... But it totally ignores my data-main attribute setting and just resolves /PAWS/Home/ to be the baseUrl.  What am I doing wrong?</p>
