Connection


PropertyDescription

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.
UseVirtualHostingIf true (default), buckets will be referenced in the request using the hosted-style request: http://yourbucket.s3.amazonaws.com/yourobject. If set to false, the bean will use the path-style request: http://s3.amazonaws.com/yourbucket/yourobject. Note that this property will be set to false, in case of an S3 based custom service when the CustomURL is specified.
