FormsAuthentication解密 无法验证数据

[kln78]

在IIS上配置两个网站，一个是localhost:801 一个是localhost:802

801上的登录页面，做了forms验证 进行了加密，在802里进行FormsAuthentication.Decrypt(cookie.value).时说无法验证

801如下web.config
<authentication mode="Forms">
</authentication>
801验证代码
DateTime expirationDate = DateTime.Now.Add(FormsAuthentication.Timeout);

FormsAuthenticationTicket ticket = new FormsAuthenticationTicket(
1,
TextBox1.Text,
DateTime.Now,
expirationDate,
true,
string.Format("{0}{1}{2}{1}{3}", SecurityValidationKey, "|", TextBox1.Text, TextBox2.Text),
FormsAuthentication.FormsCookiePath
);

string encryptedTicket = FormsAuthentication.Encrypt(ticket);

HttpCookie cookie = new HttpCookie(FormsAuthCookieName, encryptedTicket);
cookie.Expires = true ? expirationDate : DateTime.MinValue;
cookie.HttpOnly = true;
cookie.Path = "/";
cookie.Domain = "localhost";
Response.Cookies.Set(cookie);

802解密代码
var cookie = Request.Cookies["aaa"];
var ticket = FormsAuthentication.Decrypt(cookie.Value);

802能获得cookie的值，但是解密出错
