| Property | Description |
| Buckets | A list of buckets comma-delimited (ex: bucket1,bucket2,..). If left empty, ListAllMyBuckets operation will be used to find them automatically. |
| CustomURL | The custom URL to the S3 based service. Specify this URL if the S3 based service has a different URL from the 'amazonaws.com'. Make sure to specify the full URL. For example: CustomURL=http://127.0.0.1:9000. Please note that in a custom S3 based service, views other than Buckets and Objects might not be supported to work with or might need to be configured on the custom service itself. |
| STSEndpointOverride | The endpoint that the driver will use for the AWS STS service. If the protocol is missing from the URL, https:// will be used. If this parameter is not specified, the driver uses the default AWS STS endpoint. |

| UseVirtualHosting | If true (default), buckets will be referenced in the request using the hosted-style request: http://bucket-name.host/yourobject. If set to false, the bean will use the path-style request: http://host/bucket-name/yourobject. |
