kuotai commented on TS-621:
---------------------------
In http procotol, we verify receiving remote response only by Content-Length or
chunk. so if body length is 0 and no Content-Length, we can`t verify receiving
all response data. one selection, we suppose receiving all reponse data; the
other, we suppose not receiving all with some tcp errors. In most cases, we can
cached response which only having length info.
> writing 0 bytes to the HTTP cache means only update the header... need a new
> API: update_header_only() to allow 0 byte files to be cached
