You are developing an ASP.NET MVC 2 Web Applicationthat displays daily blog posts. 
Visitors access a blog post page by using a Web address to pass in the year, month, and day -for example,
contoso.com/2010/07/20.
The application must register the appropriate routeto use the Display action of the blog controller. 
Only page visits with a four digit year, two-digit month and two-digit dat can be passed to the action. 
You need to ensure that the route is registered correctly, 
Which code segment should you add?
