In the ASP.net MVC 3 project, we can use the following notation to implement permanent redirection as needed:

The code is as follows	Copy Code
Public ActionResult Index () { Return redirectpermanent ("contact"); Return redirecttoactionpermanent ("contact"); Return redirecttoroutepermanent ("contact"); }
