名字就是ASP.Login，在这个控件中有两个常用的Event， OnAuthenticate就是核实登录密码的，OnLoggedIn 就是管理登录后的事，比如Cookies，跳转到页面等等。
页面布置都放在下面的<LayoutTemplate>之中， 登录时候点击的按钮要声明，CommandName="Login" 这样按钮就和前面的事件联系起来了。此外，在OnAuthenticate的事件响应中，Argument是AuthenticateEventArgs，把这个变量的e.Authenticated属性设置为True，就可以标志用户已经进入系统的。反之，就是被拒绝。
在网页中，用this.User.Identity.IsAuthenticated来检查用户的Login状态。

asp.net login control
1. event OnAuthenticate: check login name and password, if ok, set e.Authenticated to true
protected void Login_User_Authenticate(object sender, AuthenticateEventArgs e)
{
bool Authenticated = false;
string compoundName = ConvertUserName(this.Login_User.UserName);
Authenticated = AuthenticateUser(compoundName, this.Login_User.Password);
e.Authenticated = Authenticated;
}
2. event OnLoggedIn
check if remember me on this computer. If it is, set cookies
