The bucket owner and only the bucket owner can set the RequestPaymentConfiguration.payer configuration value of a bucket to BucketOwner, the default, or Requester. Setting the requestPayment resource is optional. If you don't, the bucket, by default, is a non-Requester Pays bucket.

You use the value, BucketOwner, to revert Requester Pays buckets to regular buckets. Typically, you would use BucketOwner when uploading data to the Amazon S3 bucket, then set the value to Requester before publishing the objects in the bucket.

If the request succeeds, Amazon S3 returns a response similar to the following.

HTTP/1.1 200 OK
x-amz-id-2: [id]
x-amz-request-id: [request_id]
Date: Wed, 01 Mar 2009 12:00:00 GMT
Content-Length: 0
Connection: close
Server: AmazonS3
x-amz-request-charged:requester

Notice that you can only set Requester Pays at the bucket level; you cannot set Requester Pays for specific objects within the bucket.

You can freely configure a bucket to be BucketOwner or Requester at any time. Realize, however, that there might be a small delay, on the order of minutes, for the configuration value to take effect.

	Note
	Bucket owners who give out pre-signed URLs should think twice before configuring a bucket to be Requester Pays, especially if the URL has a very long expiry. The bucket owner is charged each time the requester uses pre-signed URLs that use the bucket owner's credentials.
