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 {{HTTPHeader("Range")}} header of the request.

The format of the response depends on the number of ranges requested. If a single range is requested, the {{HTTPHeader("Content-Type")}} of the entire response is set to the type of the document, and a {{HTTPHeader("Content-Range")}} is provided. If several ranges are requested, the {{HTTPHeader("Content-Type")}} is set to multipart/byteranges, and each fragment covers one range, with its own {{HTTPHeader("Content-Range")}} and {{HTTPHeader("Content-Type")}} headers describing it.
