title: What's the exact meaning of "session" in haproxy?
body: <p>When I open the haproxy statistics report page of my http proxy server, I saw something like this:</p>
  
  <pre><code>Cum. connections:   280073
  Cum. sessions   :   3802
  Cum. HTTP requests: 24245
  </code></pre>
  
  <p>I'm not using 'appsession' and any other cookie related command in the configuration. So what's 'session' means here?</p>
  
  <p>I guess haproxy identify http session by this order:</p>
  
  <ol>
  <li>Use cookie or query string if it's exists in the configuration.</li>
  <li>Use SSL/TLS session.</li>
  <li>Use ip address and TCP connection status.</li>
  </ol>
  
  <p>Am I Right?</p>
