The HTTP 206 Partial Content
success status response code indicates that the request has succeeded and the body contains the requested ranges of data, as described in the Range
header of the request.
If there is only one range, the Content-Type
of the whole response is set to the type of the document, and a Content-Range
is provided.
If several ranges are sent back, the Content-Type
is set to multipart/byteranges
and each fragment covers one range, with Content-Range
and Content-Type
describing it.
