When an HTTP message includes the content of multiple ranges (for example, a response to a request for multiple non-overlapping ranges), these are transmitted as a multipart MIME message. The multipart media type for this purpose is called "multipart/byteranges".
The multipart/byteranges media type includes two or more parts, each with its own Content-Type and Content-Range fields. The parts are separated using a MIME boundary parameter.
Media Type name: multipart Media subtype name: byteranges Required parameters: boundary Optional parameters: none Encoding considerations: only "7bit", "8bit", or "binary" are permitted Security considerations: none
