title: Does boost::asio use ssl session cache?
body: <p>For example, I develope email client.
  I know that some servers, for example, <em>imap.gmail.com</em>, cache SSL sessions. So I want reuse SSL sessions (from cache on my side) to reduce server load.</p>
  
  <p>I use <em>boost::asio</em> as network engine.
  Questions are:</p>
  
  <ol>
  <li>if <em>boost::asio::ssl::stream</em> doesn't use the ssl-session-cache,
  how can I enable it?</li>
  <li>if <em>boost::asio::ssl::stream</em> use the
  ssl-session-cache, how can I turn it off? :)</li>
  </ol>
