Socket reuse question

[Tamás Barta]

Hi!

I'm using httpclient-4.5.2.redhat-2.jar and I have a question I hope
somebody can explain for me.
I use this simple sample code to connect to a server a few times:

try (CloseableHttpClient client = HttpClients.custom().build()) {
  for (int i=0; i<20; i++) {
    try (CloseableHttpResponse response = client.execute(new HttpGet("
https://www.amazon.com";))) {
      System.out.println("Executed: " + getStatusCode(response));
    }
  }
}

I use "netstat" to check the outgoing connections. For almost every url I
tried netstat connections only increase by 1 and it is very well.

But when I use url "https://www.google-analytics.com/collect"; then every
get request creates a new connection and I can see 20 new TIME_WAIT rows in
netstat.

I tried everything the find out what makes the difference, but I can't. I
wonder how can I achieve that GA connections would be reused too. If I turn
logging on there is no difference in the logs for both urls.

Thanks, Tamás
