利用ASP.NET怎么实现一个注销功能

/// <summary>
/// LogoutHandler 的摘要说明
/// </summary>
public class LogoutHandler : IHttpHandler,IRequiresSessionState
{
  public void ProcessRequest(HttpContext context)
  {
    context.Session.Clear();  //从会话状态集合中移除所有的键和值
    context.Session.Abandon(); //取消当前会话

    context.Response.Redirect("/account/login.aspx");  //跳转登录页
  }

  public bool IsReusable
  {
    get
    {
      return false;
    }
  }
}
