Hi

I was wondering if it's possible to determine whether or not a viewer is logged into the backoffice or not without hitting the database.

For a long time I've been using the following code in the small amount of circumstances in which I've needed to know it:

var auth = new HttpContextWrapper(HttpContext.Current).GetUmbracoAuthTicket();
if (auth == null)
{
    return false;
}

var backofficeUser = ApplicationContext.Current.Services.UserService.GetByUsername(auth.Name);
return backofficeUser != null;

However I now need to determine if a viewer is logged into the backoffice or not on all pages, meaning a method that does not hit the database (UserService initializes and uses a database repository) would be far more ideal.

I've attempted UmbracoContext.Current.Security.ValidateCurrentUser() however this returns false on the front-end (It depends on HttpContext.Current.GetCurrentIdentity(bool) which returns null on the front-end for some reason).
