How-to: 301 Permanent Redirect with ASP.NET 4 – Response.RedirectPermanent()

During the process of migrating development over to the .NET 4 Framework there have been noticeable improvements.

One of the newest improvements is used quite often, Response.RedirectPermanent(). This new feature does a permanent redirection from a requested URL to a specified URL.

For a quick flashback to how this was previously completed review the code below:

/*
 * Previous 301 Permanent Redirect
 * */
Response.Status = "301 Moved Permanently";
Response.AddHeader("Location", "NewPage.aspx");

How you implement the new 301 Permanent Redirect is simply Response.RedirectPermanent(“URL-path-goes-here”). Here is an example with the new way with fewer lines of code.

/*
 * .NET 4 301 Permanent Redirect
 * */
Response.RedirectPermanent("NewPage.aspx");

By implementing 301 redirects it is a good practice to inform search engines that content has moved to a new location. Here are examples where Force 5 is involved with 301 redirects:
