The 206 (Partial Content) status code indicates that the server is successfully fulfilling a partial GET request for a resource. This is used by clients that support resumable downloads, allowing them to continue a download that was previously interrupted or to split a large download into multiple concurrent streams.

The response MUST include a Content-Range header field indicating the range included with this response. If multiple ranges were requested, the response will either include a multipart/byteranges content-type with a body containing each requested range, or a single range in which case only a single Content-Range header is included.
