# How to check whether a session exists or not?

How to [check whether](https://www.mindstick.com/forum/157543/write-a-java-program-to-check-whether-a-string-is-a-palindrome) a [session](https://www.mindstick.com/articles/12042/session-in-c-sharp) [exists](https://www.mindstick.com/forum/158947/how-do-you-use-the-exists-operator-to-check-for-the-existence-of-records-in-a-subquery) or not?

I want to do this on each [page](https://www.mindstick.com/articles/13031/why-to-make-a-wikipedia-page), if not exist I will just send the [user](https://www.mindstick.com/articles/13001/multi-statement-table-valued-user-defined-function-in-sql-server) back to the sign in page. ![How to check whether a session exists or not?](https://www.mindstick.com/app_images/htmleditor.icons/eusa_whistle.gif)\

Use this code for Session_Start event in global.asax file:

```
void Session_Start(object sender, EventArgs e)
    {
        if (User.Identity.IsAuthenticated)
        {
            System.Web.Security.FormsAuthentication.SignOut();
            System.Web.Security.FormsAuthentication.RedirectToLoginPage();
        }
    }
```
