metadataDirective

Specifies whether the metadata is copied from the source object or replaced with metadata that's provided in the request. When copying an object, you can preserve all metadata (the default) or specify new metadata. If this header isn’t specified, COPY is the default behavior.

General purpose bucket - For general purpose buckets, when you grant permissions, you can use the s3:x-amz-metadata-directive condition key to enforce certain metadata behavior when objects are uploaded. For more information, see Amazon S3 condition key examples in the Amazon S3 User Guide.

x-amz-website-redirect-location is unique to each object and is not copied when using the x-amz-metadata-directive header. To copy the value, you must specify x-amz-website-redirect-location in the request header.
