Ideally, you should destroy Session by calling Session.Abandon() method on logout.

During
Logoffyou should useSession.Abandon()to set all session variable to null and InPage_Loadyou should check like thisif(Session["UserName"] ==null ) Response.Redirect("Login.aspx");If you need to learn more about session, please read this article Exploring Session in ASP.Net[^] Let me know if you need more help :)Abhijit Jana | Codeproject MVP Web Site : abhijitjana.net Don't forget to click "Good Answer" on the post(s) that helped you.

Let me first understand the problem here - First, you had not validated the session on the main page hence when you entered the URL the main page was displayed. So, you validated the session variable and redirected the user to Login page. Now on the login page only after you sign-in you are able to go to the main page. Now you wish to log-out the user for which you use
session["UserName"] = null;but the main page still goes thro'. Am I correct? The problem here is that you should not usesession["UserName"] = null;to remove the session variable. You should useSession.Remove("UserName");HTH! -

Check Session Value on Page_Load. Check my Answer :)

Then the problem could be with Cache. Did you tried the above solution?

That means Session value is not null. See what is the value of Session.

1. How do you check the Session variable on the main page? If possible post the code here. 2. Does the user actually click the Logout button/link?

1.) if (Session["UserName"] == null) { Response.Redirect("Login.aspx"); } this in main.aspx page_load 2.)sure and the code to logout is :- //Session["UserName"] = null; //Session.Abandon(); Session.Remove("UserName"); Response.Redirect("Login.aspx");

Did you step thro' and check what happens in the Page_Load on the main page. Check if Session["UserName"] evaluates to null or if it returns any other value. Are you checking this with-in a IsPostBack check? Can you post the entire Page_Load code? Can you re-phrase what is happening against what is expected?

Please check if session is removed properly.. Check
Session.Remove("UserName");
var session = Session["UserName"];Check what you see in the session variable. If it is null, I think the session is somewhere created. If you can see the value of session, it is indeed not clearing out properly. Are you using webdev environment. I recommend you to try this in the IIS. :)
