Thanks for the reply André.
I am taking my terminology from RFC 2616 so "chunk-extension" should be the
right terminology I think.
I don't think multiparting would be the way to go in this case. Really with the
chunking extensions the idea for me would be to mid-request be able to
communicate between client and server. The request will be fairly long lived
and
involves a lot of data being transferred.
Chunked-Body = *chunk
last-chunk
trailer
CRLF
chunk = chunk-size [ chunk-extension ] CRLF
chunk-data CRLF
chunk-size = 1*HEX
last-chunk = 1*("0") [ chunk-extension ] CRLF
chunk-extension= *( ";" chunk-ext-name [ "=" chunk-ext-val ] )
chunk-ext-name = token
chunk-ext-val = token | quoted-string
chunk-data = chunk-size(OCTET)
trailer = *(entity-header CRLF)

Hi.
I have never heard of the term "chunk extension" before in a HTTP context.
Are you sure that this is the right term for what you are trying to find, or
achieve ?
Maybe that is why you are not finding any information ?
Maybe you talking about a POST in "multipart/form-data" format ?
(and a response in a similar multi-part kind of format, although that would
cause problems with most browsers)
