跨域用cookies好一些，象楼上的说的
不过最好加一下密

Cookie

cookie
<%@ language="C#" %>
<HTML>
<script language="C#" runat="server">
void WriteClicked(Object Sender, EventArgs e)
{
//创建一个新Cookie，其cookie名来自于NameField.Text
HttpCookie cookie = new HttpCookie(NameField.Text);

//设定Cookie的值
cookie.Value = ValueField.Text;

//设定cookie生命为1 minute，TimeSpan()是一个专门设定时间间隔的类，我们定义了其实例tsMinute
DateTime dtNow = DateTime.Now;
TimeSpan tsMinute = new TimeSpan(0, 0, 1, 0);
cookie.Expires = dtNow + tsMinute;

//添加Cookie
Response.Cookies.Add(cookie);

Response.Write("Cookie written. <br><hr>");
}
</script>
<body>
<h3>
Use the button below to write cookies to your browser
</h3>
The cookies will expire in one minute.
<form runat="server" ID="Form1">
Cookie Name
<asp:textbox id="NameField" runat="server" />
<br>
Cookie Value

图1
Listing 2 这个文件是为了读取刚才写入的cookie值
<%@ language="C#" %>
<script runat="server">
void ReadClicked(Object Sender, EventArgs e)
{
//取得想要的Cookie名
String strCookieName = NameField.Text;

//取得此Cookie名对应的对象，注意目前的得到的cookie是个对象
HttpCookie cookie = Request.Cookies[strCookieName];

//检验Cookie是否已经存在
if (null == cookie) {
Response.Write("Cookie not found. <br><hr>");
}
else {
//显示Cookie的值
String strCookieValue = cookie.Value.ToString();
Response.Write("The " + strCookieName + " cookie contains: <b>"
+ strCookieValue + "</b><br><hr>");
}
}
</script>
<html>
<body>
Use the button below to read a cookie

<form runat="server" ID="Form1">

Private Function CreateAuthTicket(ByVal userName As String, ByVal roles As String, _
ByVal persistent As Boolean) As FormsAuthenticationTicket
Return New FormsAuthenticationTicket(1, userName, DateTime.Now, _
DateTime.Now.AddMinutes(60), persistent, roles)
End Function
Private Function CreateAuthCookie(ByVal authTicket As FormsAuthenticationTicket) As HttpCookie
Return New HttpCookie(FormsAuthentication.FormsCookieName, _
FormsAuthentication.Encrypt(authTicket))
End Function

写在你验证的地方
Dim authTicket As FormsAuthenticationTicket
Dim authCookie As HttpCookie

IF 有这个用户意见THEN

authTicket = CreateAuthTicket(txtUserID.Text, CStr(viewstate("roles")), False)
authCookie = CreateAuthCookie(authTicket)
HttpContext.Current.Response.Cookies.Add(authCookie)
END IF

在web.config 里面增加了下面的代码. 而且也在数据库里面建立了用户表. 但是无论我用什么用户名去登陆, 都不能登陆, 请问我应该用什么用户名去登陆呢?

<authentication mode="Forms">
<forms name=".ASPXFORMSDEMO" loginUrl="login.aspx"
protection="All" path="/" timeout="1" />
</authentication>

<authorization>
<allow users="*" /> 

</authorization>
