The gateway supports SCSP reads & writes of domain and bucket headers with lifecycle policies specified. Gateway S3 interface is modified to support GET, PUT, DELETE, and related permissions (GetLifecycleConfiguration and PutLifecycleConfiguration) for bucket lifecycle policies as specified in the S3 documentation. Gateway validates policies against the S3 specification. On PUT or DELETE permission, the gateway translates the client-supplied bucket policy specifications into the appropriate Swarm bucket headers. Bucket lifecycle policy features provided via using S3 that Swarm does not support not supported by Swarm (such as storage class transitions) are dropped during this translation. On the bucket lifecycle policy GET reply, Gateway performs reverse translation for any Policy-Lifecycle headers on the bucket object into an S3-compatible format.
