title: Any way to set access-control-allow-origin for a windows azure blob
body: <p>I am storing json blobs on azure which I am accessing via XHR. While trying to load these blobs I am getting this error:<br>
  XMLHttpRequest cannot load <a href="http://myazureaccount.blob.core.windows.net/myjsoncontainer/myblob.json?json" rel="noreferrer">http://myazureaccount.blob.core.windows.net/myjsoncontainer/myblob.json?json</a>. Origin <a href="http://localhost" rel="noreferrer">http://localhost</a> is not allowed by Access-Control-Allow-Origin.</p>
  
  <p>Is there any way to set the <a href="https://developer.mozilla.org/en/HTTP_access_control#Access-Control-Allow-Origin" rel="noreferrer">Access-Control-Allow-Origin</a> header of a blob returned by azure?</p>
