As I know asp.net does it automatically if you have LoginUrl set in your forms section in the web.config

Solution 2

In Web.config

XML

<authentication mode="Forms">
      <forms loginUrl="login.aspx" defaultUrl="homePage.aspx" timeout="yourTime" name="UserLogin" path="/"/>
    </authentication>

In login.aspx.cs

FormsAuthentication.RedirectFromLoginPage(username, persistent cookie?)

Hi,

You can implement Form authentication which is cookie based and cookie will expire after the timeout set in config file and user will be redirected to the given page.

Refer below links for implementing form based authentication.

http://support.microsoft.com/kb/301240[^]
Understanding and Implementing ASP.NET Custom Forms Authentication[^]
Role-based Security with Forms Authentication[^]

Or set user session after login and check user session in each page or create a base class in each page in which you can check user session.

Hope this will help you.
