Explain about Response.RedirectPermanent() method in ASP.NET 4.0 ?

Answer:

Below is an example which explains this method clearly.

Example:

The advantage of this method is that, the search engines will remove old page from its cache/database and will take this permanent redirection (Status 301). And also includes new page for better performance on search.
