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)
        SessionUtility.UpdateDatabase(Convert.ToInt32(Session["UserHistoryID"]));

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

Why is this happening?

Some one please explain how the Session_End works exactly.

I have searched everywhere but can't find a solution to this.

If I declare a variable for each session value I want to access in the Session_End event and store the value of the session in this variable and use the declared variable in the my functionality it is working fine

void Session_End(object sender, EventArgs e)
{
   int var=0;
   if (Session["value"] != null)
   {
      var = Convert.ToInt32(Session["value"]);
      UpdateToDatabase(var);
   }
}

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)
            {
                Response.Write(Session["language"].ToString());
            }
        }
    }

hopefully that would help !!
