Hi,
There appears to be some confusion as to when multipart/byteranges
bodies have to be inspected to determine the message length. It seems
that is widely considered optional and sometimes limited to ...
In general, HTTP treats a multipart message-body no differently than
any other media type: strictly as payload. The one exception is the
"multipart/byteranges" type (appendix 19.2) when it appears in a 206
(Partial Content) response ...
... this particular case, even though the specification suggest the
opposite, I read it to say, all implementations have to support that
and support it in all messages, like requests and non-206 responses.
Apache 2.2.6 for example treats
POST / HTTP/1.1
Host: example
Content-type: multipart/byteranges;
boundary=THIS_STRING_SEPARATES
--THIS_STRING_SEPARATES
...
as two requests, a zero-length POST and a --THIS_STRING_SEPARATES to
the root which it does not support (which seems to be a bug in itself).
Would it be possible, for example, to discourage implementations to
ever generate messages where the message length is determined by this
type, and limit having to read it to 206 responses, as the text above
suggests?
regards,
