i created a session if the user is authenticated like this

if (HttpContext.Current.User.Identity.IsAuthenticated)
    {

        string name = HttpContext.Current.User.Identity.Name.ToString();
        Session["username"] = name;
    }

then i am checking if the session still exit like this

  if (Session["username"] == null)
            Response.Redirect("SessionExpired.aspx");
        else
            Response.Write("session still exist");

**the problem : **the session is not getting null after 1 min and the user is always login any help

this is the code:

     Welcome to ASP.NET! test1
     <p>
     To  visit  test2 go to<asp:LinkButton ID="LinkButton1" runat="server" 
      onclick="LinkButton1_Click">here</asp:LinkButton> 
     </p>
     <asp:Label ID="msg" runat="server" Text=""></asp:Label>

in server side

    protected void LinkButton1_Click(object sender, EventArgs e)
   {
     if (HttpContext.Current.User.Identity.IsAuthenticated)
    {

    string name = HttpContext.Current.User.Identity.Name.ToString();
    Session["username"] = name;
    if (Session["username"] == null)
        Response.Redirect("~/SessionExpired.aspx");
    else

 msg.Text = "session still exist the session will be timedout after "+Session.Timeout+ "min";
 }
 else
    Response.Write("please login");
 }

the session should time out after 1 min of inactivity. Are you doing any postbacks or any activity?

There is no chance to be Session["username"] object to null. so if statement useless..

string name = HttpContext.Current.User.Identity.Name.ToString();
    Session["username"] = name;
    if (Session["username"] == null)
        Response.Redirect("~/SessionExpired.aspx");

how can i check if the session is expired?? if (Session["username"] == null) isn't that mean if the session variable is expired:o ?

hkutluay Over a year ago

you can check session expired before assign a value to session. not after. I mean that if statement should be upper than Session["username"] = name; line.

@bassem ala:though you are setting session time out period in configuration file by default asp.net checks servers session time out value.you have to manually set session values null after one minute.
