Answer 1

使用FormsAuthentication验证机制，必须在wei.config中配置authentication
例：
<authentication mode="Forms">
<forms cookieless="AutoDetect" loginUrl="~/User/Default.htm" name="SUMINGER" domain="jj-it.com"></forms>
</authentication>

Answer 2

除此之外，还要设置目录权限
<location path="Master">
<system.web>
<authorization>
<deny users="?"></deny>
</authorization>
</system.web>
</location>

Answer 3

手工的自己写的<authentication mode="Forms"> 
<forms  loginUrl="~/User/Default.htm" name="SUMINGER" DefaultURL="登陆成功后页面"></forms> 
</authentication>

Answer 4

 Response.Redirect("~/index.aspx"); 
路径对吗
