Html 使用web.config中的位置进行http重定向循环

我有一个网站，里面有一个我想保密的目录。我的登录页面位于名为admin.aspx的目录中

在我的主Web.Config中，我有以下块：

<authentication mode="Forms">
  <forms loginUrl="~/Account/admin.aspx" name=".ASPXFORMSAUTH"></forms>
</authentication>

我不明白为什么它会陷入一个循环。如果我将web.config（在目录中）更改为：

  <system.web>
    <authorization>
      <allow users="*"/>
    </authorization>
  </system.web>

我能找到它，那么它有位置选项吗

谢谢
