+NOTE: To be handled transparently, the `Resource` object must not be a `InputStreamResource` and, in case of an annotated controller returning `ResponseEntity<Resource>`, the status of the response must be 200.

 The underlying support is in the `HttpRange` class, which exposes methods to parse
 `Range` headers and split a `Resource` into a `List<ResourceRegion>` that in turn can be
 then written to the response via `ResourceRegionHttpMessageConverter`.
