expiration

val expiration: String?

If the object expiration is configured (see PutBucketLifecycleConfiguration), the response includes this header. It includes the expiry-date and rule-id key-value pairs providing object expiration information. The value of the rule-id is URL-encoded.

Object expiration information is not returned in directory buckets and this header returns the value "NotImplemented" in all responses for directory buckets.
