title: Clear session in logout.ashx
body: <p>I have an ashx handler and want to clear the session on request. I am getting object not set to instance of object on the Session.Abondon() line. I am trying to logout a user.</p>
  
  <pre><code> public void ProcessRequest (HttpContext context) {
      //context.Response.ContentType = "text/plain";
      //context.Response.Write("Hello World");
      FormsAuthentication.SignOut();
      context.Session.Abandon();
      context.Response.Redirect("/login.aspx");        
   } 
  </code></pre>
  
  <p>Am I doing something wrong?</p>
