Sorry for the late and possibly ignorant response. Is what you’re trying to accomplish already possible with the use of multipart/byteranges?



e.g.

- Client requests stream starting from byte 0 of an unknown length.

- Server responds in N-KByte buffers (e.g. 1K) of data from a stream of unknown length (chunking not shown for brevity)

- Response ends at the end of stream or when the client closes the connection to seek to a new location





GET /path/file HTTP/1.1

Host: example.com

Range: bytes=0-





HTTP/1.1 206 Partial Content

Date: Wed, 15 Nov 1995 06:25:24 GMT

Last-Modified: Wed, 15 Nov 1995 04:58:08 GMT

Transfer-Encoding: chunked

Content-Type: multipart/byteranges; boundary=THIS_STRING_SEPARATES



--THIS_STRING_SEPARATES

Content-Range: bytes 0-1023/*



...the first range...

--THIS_STRING_SEPARATES
