正确使用身份验证，并在web.config文件中将登录页面设置为login.aspx。你不用担心。 Asp.net身份验证将自动执行。请参阅以下链接：

Hi,

Use authentication properly and set the login page to login.aspx there in web.config file. You don't need to worry. Asp.net authentication will do it automatically. Refer these links:
From Custom Authentication to ASP.NET Forms Authentication[^]

All the best.

if ((HttpContext.Current.Request.UrlReferrer == null))
{
    Response.Redirect("Default.aspx");
}

如果我有project.aspx和login.aspx



在你的project.aspx.cs上页面加载

只需写一下



if（（HttpContext.Current.Request.UrlReferrer == null） ）

{

Response.Redirect（login.aspx）;

}



这会将你重定向回登录页面。

希望这能解决你的问题。

"If I have project.aspx and login.aspx"

On your project.aspx.cs Page Load
simply write

if ((HttpContext.Current.Request.UrlReferrer == null))
{
Response.Redirect("login.aspx");
}

This will redirect you back to Login page.
Hope this solves your problem.
