Session variable value not always available in Global.asax Session_end

When a user logs into the website, I am creating 5 session variables with some user related values (like userid,roleid etc..). Based on one of the values stored in a session variable, I have to update a record in the database. To do this I am writing the following code in the Session_End() event of Global.asax

if (Session["UserHistoryID"] != null)


The problem here with this is when the Session times out and Session_End fires the Session variable Session["UserHistoryID"] is NULL some-time and the above condition fails and the record in the database is not updated. When this is tested in my local system it works fine but when I test this in production server some of the records are not getting updated

Some one please explain how the Session_End works exactly.

    I think that the earliest possible time you could obtain the Session value is under Application_AcquireRequestState as mentioned hereSessions and Global.asax so you could write something like this in your Global.asax

    void Application_AcquireRequestState(object sender, EventArgs e)


            if (System.Web.HttpContext.Current.Session != null)


                if (Session["language"] != null)






    hopefully that would help !!
