title: Origin header missing from cross origin request to S3 on Chrome
body: <p>I am trying to load an asset (a font) from an s3 bucket. Fonts on Firefox and IE need to have Access-Control-Allow-Origin headers returned in the response. Unfortunately it seems that Chrome is not sending an "Origin" request header. Since it is not sending an Origin request header, S3's CORS policy is not returning the required Access-Control-Allow-Origin header.</p>
  
  <p>Here is an example request screenshotted from the Chrome inspector panel:</p>
  
  <p><strong>Why is there no "Origin" Header in the Requset Headers?!</strong></p>
