title: CORS with SPServices + jQuery
body: <p>I need to access from a different domaine on a mobile a sharepoint list. Here is my code, a simple get request :</p>
  
  <pre><code>$.support.cors = true;
  
  $(function() {
  $().SPServices({
      operation: "GetListItems",
      webURL: "http://myurl.com/project/",
      listName: "PM-Registration",
      CAMLQuery: '&lt;Query&gt;&lt;/Query&gt;',
      error: function (xhr, message, error) {
            alert('error : ' + error);
      },
      completefunc: function (xData, status) {
          alert('Status: '+status+' xdata: ' + xData.statusText);
          alert('RESPONSE: ' + xData.responseText);
      }
  });
  });
  </code></pre>
  
  <p>The problem seems to be CORS blocking the request, but I normally enable it before.
  It works perfectly with Chrome if I use the command : --args --disable-web-security, and with Safari desktop, but not with Firefox and Safari iOS...
  I got the error on Chrome without disabling web security :</p>
  
  <pre><code>No 'Access-Control-Allow-Origin' header is present on the requested resource
  </code></pre>
  
  <p>Am I missing something ? I guess it is a client side problem as it works with Chrome without web security and Safari Desktop</p>
