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