Keep-alive is used for sure. I would expect the connection to be kept open unless you call disconnect. But you are creating a new HttpURLConnection each time and then discarding it. I'm not sure how the connection pooling works under the hood within the JVM. It used to be difficult to get the JVM to release a connection and actually terminate the TCP/IP connection. http://docs.oracle.com/javase/8/docs/technotes/guides/net/http-keepalive .html Pay close attention to the remarks about stream-handling. Tomcat may close the connection under certain circumstances, usually error-related. If you are getting 200 OK responses from Tomcat, then I'm not sure why the TCP/IP connection would be dropped, unless Java thinks that 30 seconds is too long of an idle time to keep those connections open.
