Two system properties have been added which control the keep alive behavior of HttpURLConnection in the case where the server does not specify a keep alive time. Two properties are defined for controlling connections to servers and proxies separately. They are `http.keepAlive.time.server` and `http.keepAlive.time.proxy` respectively. More information about them can be found at: https://docs.oracle.com/en/java/javase/17/docs/api/java.base/java/net/doc-files/net-properties.html
