body: <p>Ive been having problem with uploading on Azure Blob Storage. Im able to generate SAS Token but when I do request an upload, it returns an error saying:</p>
  
  <pre><code>XMLHttpRequest cannot load 
  https://mycureresources.blob.core.windows.net/resources/test.jpeg?st=2016-0…BZj6%2FKcVWRvoLXkKfa109EV6%2FYuwmTs%3D&amp;comp=block&amp;blockid=YmxvY2stMDAwMDAw. 
  Response to preflight request doesn't pass access control check: No 'Access-Control-Allow-Origin' 
  header is present on the requested resource. Origin 'http://czar.opie.com:3210' is therefore not allowed access.
  The response had HTTP status code 403.
