You described a scenario (and quoted the corresponding RFC) that not
just presumes the existence of persistent connections, but where they
are the default - hence the need to use 'Connection: close' when you
don't want them.
The point here is that without a reliable Content-Length: header, "after
receiving the response" <=> "the server has closed the connection".

Good luck in making that point - since it provably didn't. There *are*
problems with this approach, see the caveat in my statement - but they
are not attributes of TCP or the standard socket API.

Well, conspiracy theories and M$-bashing is always fun, but I think you
need a reality check here...

Sure - but it's not relevant here.
