Redirect to specific page after session expires (MVC4)

Question

C# MVC4 project: I want to redirect to a specific page when the session expires.

After some research, I added the following code to the Global.asax in m

Answer 1

This is some something new in MVC.

    Public class SessionAuthorizeAttribute : AuthorizeAttribute
    {
        Protected override void HandleUnauthorizeRequest( 
                                   AuthorizationContext filtercontext )
            { 
                filtercontext.Result = new RedirectResult("~/Login/Index");
            } 
    }

After apply this filter on your controller on those where you want to apply authorization.

    [SessionAuthorize]
    public class HomeController : Controller
    {
        // Something awesome here.
    }

Above SessionAuthorizeAttribute's HandleUnAuthorizeRequest function will only call once authorization is failed Instead of repeatedly check for authorization.
