title: Sencha Touch - Cross Domain (CORS) Issue
body: <p>I am attempting to load datapoints from a cross domain URL. Unfortunately I can't get this to work. I have set up my Apache Linux server to support CORS as far as I can tell. I added the following to the header of the configuration file:</p>
  
  <pre><code>Header set Access-Control-Allow-Origin "*"
  Header set Access-Control-Allow-Methods "GET,POST"
  Header set Access-Control-Allow-Headers "X-Requested-With"
  </code></pre>
  
  <p>This is the current setup of my store:</p>
  
  <pre><code>    var myStore = Ext.create('Ext.data.Store',
      {
              fields: [{name: 'xTime', type: 'int'}, {name: 'yData', type: 'float'}, {name: 'target', type: 'string'}],
              proxy:
              {
                  type: 'ajax',
                  url: 'http://test.com/datapoints.json',
                  useDefaultXhrHeader: false,
                  reader: 'points'
              },
              autoLoad: true
      });
  </code></pre>
  
  <p>I'm just trying to find what am I missing here? I'm testing it using Safari and so far, I'm still getting the "Access-Control-Allow-Origin" error.</p>
  
  <p>Any help would be greatly appreciated!</p>
