By default, buckets do not have lifecycle management enabled. To set or
modify lifecycle configuration for an existing bucket you make a PUT request
that is scoped to the bucket and you use the lifecycle query string
parameter. You must include an XML document in the request body that contains
the lifecycle configuration. Notice that you cannot set lifecycle configuration
on a new bucket that you are creating.
You must have FULL_CONTROL permission to set or modify lifecycle
configuration for an existing bucket. Also, you must be authenticated to use the
PUT Bucket method.
Query string parameters
