This patch does not work (reliably):
* I have never seen EarlyResponseException
* When run over HTTPS I see early responses somtimes, sometimes
I
get
SSLException
* Via HTTP I never see an early response, but only
SocketException
Buffers again? Note that curl reads the physical response in
any
case.
See output here:

I do not want to give up yet. Could you please try out this
patch?

Apologies, I made a mistake, since take 1 was 5.1-SNAPSHOT, I
assumed
that take2 has this version too, noticed too late that it is
5.0.1-SNAPSHOT actually.
I have redone the tests, and raised to 50 iterations. Write buffer
in
HttpEntity is 16 KiB.
732a99563e73529e0359625fda54351b843b2e34:
* Performs great on HTTP, fails really early
* Does not work with TLS 1.3 at all
8d7b2e3d38b4d696d45cde16c52dba278be15438:
* Works with HTTP, but takes a lot of payload to detect early
response
* HTTPS is a bit better, it takes around 400 kB.

I do not think it really matters if it is 0 kb or 400 kb as long as
the
server does not reset the connection and the request gets correctly
retried.
I will improve the patch further. Please bear with me.
Please try out this patch. This should now give us proper out of
sequence response check with minimal overhead. The check will now be
performed for chunks of 2048 bytes instead of each and every write
operations.

This one does not work at all. It does even break the final
(authenticated) request. See for yourself:
