Question

I have 2 pages on my dummy site in asp.net, (default.aspx and default2.aspx), On default.aspx, i created session like below

   protected void Page_Load(object sender, EventArgs e)
    {
        Session["MySession"] = "WELCOME";
        Session.Timeout = 1;
    }
    protected void Button1_Click(object sender, EventArgs e)
    {
        Response.Redirect("default2.aspx");
    }

and on default2.aspx

 if (Session["MySession"] != null)
            Response.Write(Session["MySession"]);
        else
            Response.Write("Session Timed Out");

i was wondering that after 1 min the session will get erase, as i have timeout, but after one minute when i click on the button it redirected me to default2.aspx, and displayed a session value “WELCOME”. can anyone tell me how to erase session value after particular duration

Answer 1

In your Default.aspx you have to check if it is not a post back otherwise the session will be initialized again for each button click

 protected void Page_Load(object sender, EventArgs e)
  {
     if(!Page.isPostBack())
        {
          Session["MySession"] = "WELCOME";
          Session.Timeout = 1;
        }
  }

protected void Button1_Click(object sender, EventArgs e)
{
    Response.Redirect("default2.aspx");
}
