Answer 1

I think this can help you use Session in MVC app, Try this in global.asax:

protected void Session_Start()
{
    HttpContext.Current.Session.Add("superadmin", user);
}

Then in any of your controller:

user = HttpContext.Session["superadmin"];

You can either keep the data for the reqeust in the SQL database or use some sort of private static Dictionary<Request, Cart>.
