title: JSF Page Request Logging in Production using Phase Listener
body: <p>I am developing a web application and I need to log page requestes by client. So that, I implemented PhaseListener from <a href="http://www.softwareengineeringsolutions.com/thoughts/frameworks/JSF.Techniques-PhaseListeners.htm" rel="nofollow noreferrer">this link.</a></p>
  <p>In this tutorial, in <strong>final comments</strong> section which is end of the page suggests that;</p>
  <blockquote>
  <p>&quot;Using a phase listener can be a worthwhile tool during development as
  it gives you ready feedback as to what is going on within the innards
  of JSF.<br />
  Just remember to turn this diagnostic tool off in production!&quot;</p>
  </blockquote>
  <p>I don't understand why I need to turn off phase listener in production.
  <strong>Would you tell me advantages and disadvantages of using phaselistener in production ?</strong></p>
  <p>Regards.</p>
