206 Partial Content

The HTTP 206 Partial Content successful response status code is sent in response to a range request. The response body contains the requested ranges of data as specified in the Range header of the request.
The format of the response depends on the number of ranges requested. If a single range is requested, the Content-Type of the entire response is set to the type of the document, and a Content-Range is provided. If several ranges are requested, the Content-Type is set to multipart/byteranges, and each fragment covers one range, with its own Content-Range and Content-Type headers describing it.
