sequence when using non-persistance)

> Key: HTTPCLIENT-1655
> URL: https://issues.apache.org/jira/browse/HTTPCLIENT-1655
> Project: HttpComponents HttpClient
> Issue Type: Bug
> Components: HttpClient
> Affects Versions: 4.4.1
> Reporter: Alan Silva
>
> I'm seeing an interesting behavior with HttpClient 4.4.1 GA (latest release
> as of the writing of this issue) when trying to make http requests with no
> keep-alive.
> First, let me post my code for the case in which I try to request using
> keep-alive.
> <Placeholder for keepalive code attachment link>
> With the code above, everything works great. All my requests are done one the
> same connection and we get a nice graceful close with a couple FIN ACKs at
> the end. The capture is here:
> <Placeholder for keepalive capture attachment link>
> However, when I try to do the same thing without using keepalive (I set
> "Connection: close" in the httpclient and make sure I call close on the
> httpclient as well at the end of each request), I see I the client send a
> reset (RST) signal to the server at the end of the connection.
> The code for the non keepalive test is here:
> <Placeholder for no keepalive code attachment link>
> And its capture is here:
> <Placeholder for no keepalive capture attachment link>
> I don't understand why the test with non persistent connections isn't
> gracefully closing the connection as it does with the persistent use case by
> sending a FIN,ACK to the server. It instead chooses to send a RST. Am I doing
> something wrong?
> I tried the same test for no keep-alive with our legacy code using the now
> deprecated "commons-httpclient-3.1.jar" library. I see a proper connection
> close there.
> <Placeholder for no keepalive capture attachment for old httpclient link>
