<izinkan role="admins"/>//允许管理级别用户访问
</otorisasi>
sesi ASP.NET, sesi ASP.NET, dan sesi ASP.NET上所有页面都要验证才能访问,感觉有点迁强.但可以在web.config页面对指定的页面设置权限,设置代码如下
<jalur lokasi="admin.aspx">
<sistem.web>
<otorisasi>
<menolak pengguna="?" />
</otorisasi>
</sistem.web>
</lokasi>
如果只有几个页面设置如上代码,感觉还可以接受.但页面多了岂不是要把人累死呀．．
不甚感激．
