Jon.Lee :
It seems that you have your own method to store the login data for user .
So, Context.User.Identity.IsAuthenticated is not useful for you .
You can try:
public string GetUserUniqueName()
{
HttpCookie cookie=HttpContext.Current.Request.Cookies["username"];
if(cookie==null)return null;
string name=cookie.Value;
if(name==null||name=="")return null;
//TODO : check the cookie username/password again
return name;
}
