I tweeted the same thing to that account and got no response. I'm glad you did. the Access-Control-Allow-Origin header has been a heavily requested feature since 2009: https://forums.aws.amazon.com/thread.jspa?threadID=34281&start=175&tstart=0 https://forums.aws.amazon.com/thread.jspa?threadID=34281&#38... One example of how fundamental this is: you cannot currently perform a direct AJAX upload to an s3 bucket from a web application hosted on an ec2 instance. There is a postMessage hack that will work with small files, and of course you can use a proxy, but you'd think it would be a common scenario to want to upload files directly to S3.

You can upload files directly to s3 from your website: http://aws.amazon.com/articles/1434 http://aws.amazon.com/articles/1434

  This only works standalone and not embedded in an AJAX application. I only wish someone from the S3 team at Amazon would at least answer to this thread: https://forums.aws.amazon.com/thread.jspa?threadID=34281&start=175&tstart=0 https://forums.aws.amazon.com/thread.jspa?threadID=34281&#38... Hundreds of messages in this thread and no answer after 2 years and counting.

    Well, "AJAX application" is too nebulous of a term to really be meaningful here. If you mean you can't use an XHR request, sure, but you can certainly construct the necessary <input> element and POST request dynamically with JavaScript.
