/// 
public class LogoutHandler : IHttpHandler,IRequiresSessionState
{
  public void ProcessRequest(HttpContext context)
  {
    context.Session.Clear();  //                
    context.Session.Abandon(); //      

    context.Response.Redirect("/account/login.aspx");  //     
  }

  public bool IsReusable
