Dear Sir,
I already use the mediacache module to access AWS S3 (worldwide) well for a few months, it is totally fine. But I meet big problem to apply in AWS China S3. AWS China S3 only support AWS Signature Version 4 (detail information : http://docs.aws.amazon.com/AmazonS3/latest/dev/UsingAWSSDK.html). Could you prompt how to configure MediaCache to support AWS S3 signature version 4 ?
