 * 2. client sends POST with a body containing "ZZZ"
 * 3. server waits for POST and closes connection without replying
 * 4. client should re-open the connection and re-send the POST
 * 5. <bug>The client forgets to re-send the body with the POST
 *    The server hangs waiting for the body</bug>
 *
 *    <bugfixed>The client sends the body. The server reads it and the
