RemarksIf the CallerReference is a value you already sent in a previous request to create a distribution, and the content of the CloudFrontDistributionConfig is identical to the original request (ignoring white space), the response includes the same information returned to the original request.
If the CallerReference is a value you already sent in a previous request to create a distribution but the content of the CloudFrontDistributionConfig is different from the original request, CloudFront returns a DistributionAlreadyExists error.
