> 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.
> [Java code for keepalive test with httpclient 4.4.1 GA | ^KeepAliveTest.java]
> 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:
> [Capture of keepalive test with httpclient 4.4.1 GA | ^POC_keep_alive_WITHOUT_class.pcap]
> 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
> The code for the non keepalive test is here:
> [Java code for no keepalive test with httpclient 4.4.1 GA | ^NoKeepAliveTest.java]
> And its capture is here:
> [Capture of no keepalive test with httpclient 4.4.1 GA  |^POC_WITHOUT_keep_alive_WITHOUT_class.pcap]
> 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.
> [Capture of no keepalive test with commons-httpclient-3.1  |^old_code_mss.pcap]
> I've attached as much info as I can think of but if the wire logs or any other info is
needed, I'd be more than happy to append it.
