Michael, this looks a bit like the packets in between have been
TLS

Michael,
I can only second what Bernd has said. Try to simplify the setup
and
see if you can get things to work with plain HTTP first.
Also feel free to tweak my code as you see fit.
I followed Bernd's advise and disabled TLS. Although I already had a
clue what is going wrong. Attached is a patch on top of Oleg's
branch
which makes it work unencrypted and encrypted. I will explain in
detail
why the changes are necessary.
- public static final Timeout DEFAULT_WAIT_FOR_EARLY_RESPONSE =
Timeout.ofMilliseconds(5);
+ public static final Timeout DEFAULT_WAIT_FOR_EARLY_RESPONSE =
Timeout.ofMilliseconds(50);
unless client and server are physically next to each other 5 ms are
virtually impossible. I have tried with our server at work. I am
connected with my laptop via VPN to the corporate network, I don't
know
where the peering point of our VPN provider is, but the server is
physically 10 km away from me and with TLS 1.3 it takes 28 ms to
produce
the 401.
Maybe both timeouts (expect and early) should be configurable via
RequestConfig?
+ conn.flush();
Michael
You are absolutely right. Not flushing the request head was the cause
of the problem.
Could you please try out a slightly different take on your original
patch, though?
https://github.com/ok2c/httpcomponents-core/commit/39f6d69a87586c147dc080431d45d6d48acb2c80
HttpRequestExecutor ought not be flushing all request message heads
indiscriminately and should still try to pack small payload messages
into a single IP frame for performance reasons.
Makes sense!
I also would not overload RequestConfig with too many options but we
can discuss that later.
Agreed.
This is why it did not work before is that headers were stuck in the
local buffer and were flushed only when the body was sent. So the
server
never saw the headers before the body. The wait was pointless.
Please also note that even the buffer for headers might be large due
to
some authnz tokens. E.g., JWT or SPNEGO, cookies, etc.
+ response = conn.receiveResponseHeader();
One needs to read the headers because the client shall be able to
see
the status code and if fast enough the response body. In my case the
error page from Tomcat.
RFC 7230, section 6.5 says:
A client sending a message body SHOULD monitor the network
connection
for an error response while it is transmitting the request. If
the
client sees a response that indicates the server does not wish
to
receive the message body and is closing the connection, the
client
SHOULD immediately cease transmitting the body and close its
side of
the connection.
I have issued another request and HttpClient reuses the connection
because Tomcat forgot to send "Connection: close".
Hmm. That sounds weird. HttpClient must terminate the connection if it
failed to submit the entire message body declared in `Content-Length`
header. The #terminateRequest should have marked the connection as
`inconsistent`.
Could you please send me a wire log of the session?
So far, the patch works and I can access the first 401 response.
This is my test client code, if necessary:
HttpClientBuilder builder = HttpClientBuilder.create();
try (CloseableHttpClient httpClient = builder.build()) {
HttpPost method = new
HttpPost("https://<hostname>:11111/content-dev/api/documents");
method.setHeader("Connection", "blbla");
method.setEntity(new FileEntity(new File("Z:\\inputs.zip"),
ContentType.create("application/zip")) {
@Override
public void writeTo(OutputStream outStream) throws IOException {
Args.notNull(outStream, "Output stream");
try (final InputStream inStream = getContent()) {
if (inStream != null) {
int count;
final byte[] tmp = new byte[4096*2];
long writtenBytes = 0L;
while ((count = inStream.read(tmp)) != -1) {
System.out.printf("Bytes written: %d%n", writtenBytes);
outStream.write(tmp, 0, count);
writtenBytes += count;
}
}
}
}
});
CloseableHttpResponse response = httpClient.execute(method);
response.getEntity().writeTo(System.out);
response.close();
response = httpClient.execute(method);
response.getEntity().writeTo(System.out);
response.close();
}
and the output:
