title: drools stateless vs stateful session
body: <p>When should I use Drools stateless session and what are the benefits of using it instead of stateful  session?<br>
  In some comment <a href="https://stackoverflow.com/questions/28710711/drools-why-stateless-sessions">here</a> it's said that stateless sessions wraps a stateful one, does it means that when I destory the statfeul session after firing all rules would behave like a stateful one ?</p>
