This section is a red herring, since it refers to the response to an
OPTIONS request, not to a POST request itself.

Section 4.3 Message Body says

   The presence of a message-body in a request is signaled by the
   inclusion of a Content-Length or Transfer-Encoding header field in
   the request's message-headers.

What this means is, if you don't send a content length or transfer
encoding header, then the server should not expect a body. I will note,
in particular, that not sending a message is a distinct operation from
sending a message of length 0.
