How save a variable from session and get when session is null?

Question

I Write into a session user login. I need to get user login on server side page when a session is dropped. I try:

 private string currentUserLogin;
 protected void Page_Load(object sender, EventArgs e)
 {   
      if (!IsPostBack)
      {
          if (HttpContext.Current.Session["curUserRole"] == null)
          {
               // try to get a "currentUserLogin" varialbe, but it null!
          }
          else
          {
               currentUserLogin = HttpContext.Current.Session["curUserLogin"].ToString();                   
          }
      }
 }

what do you mean when session is dropped? are you trying to access session after session timeout? — Blast_dan

Where is the HttpContext.Current.Session["curUserRole"] = someValue; in your code? Do you set the session value anywhere? — RePierre

Is there a reason you aren't just making the session timeout longer so that you don't need to access it after it is expired? — Servy

Store the information from the session into cookie (with desired expiration time) & retrieve the value from cookie when session expires.

User Roles and User Logins are not for cookies, This stuff should be Database driven. However you are right in saying it can't be session stored.

In the Global.asax there is a SessionEnd event. I use it to write to write to to a log file the userID and logoff date/time.

It should be pointed out that the SessionEnd event only works when your session store is in-memory, not when you are using a State Server or SQL Server
