That's not possible in most cases: in HTTP/2 and HTTP/3 we don't send the 
content-length:0 header, we only send content-length when it's known up front 
and non-zero.
In cases where it is possible it's usually not necessary - most of the time we 
don't really care if the content length was sent or not, as long as the server 
is able to figure it out.

I'll add a check for the HTTP/1 + PUT/POST case, since that's special-cased by 
this PR.
