答

为了检查是否有人登录，请使用会话.为了重定向到请求的页面，您可以使用查询字符串.

In order to check if someone has logged in or not, use session. In order to redirect to the page which was requested for, you can use query string.

您可以在webconfig文件中使用以下内容

You can use the following in your webconfig file

<authentication mode="Forms">
    <forms name="AName" loginUrl="LoginPage.aspx" protection="All" timeout="20"/>
</authentication>

成功登录后，在登录页面中使用FormsAuthentication.RedirectFromLoginPage(username, False).

and in your login page use FormsAuthentication.RedirectFromLoginPage(username, False) once the login has been successfully carried out.
