title: Abandon procedure, or clear procedure variable?
body: <p>I was wondering whether it was better procedure to abandon a session </p>
  
  <p>e.g. <code>session.Abandon();</code></p>
  
  <p>or to clear the session variable data</p>
  
  <p><code>e.g. Session["PersonID"] = null;</code></p>
  
  <p>or would this be dependent on the situation?</p>
