Force Amazon S3 to send default Access-Control-Allow-Origin header

Question

S3 answer me the Access-Control-Allow-Originheading only if you send him Originand Access-Control-Request-Method. Is there a way that S3 will respond Access-Control-Allow-Originby default without any special headers?

Answer 1

According to the W3C CORS specification, CORS response headers should only be included if the request contains a header Origin.

S3 follows this specification, so it's impossible to get it to always send CORS response headers.
