RedirectPermanent in ASP.NET

Question

What is RedirectPermanent in ASP.NET 4.0?

Prabhu Raja · Answer

Hi, ASP.NET 4 introduces the RedirectPermanent method. Search engines can store the new URL associated with the content removing the need to use the Redirect method for moved content. This method can be used to move to the new link: Response.RedirectPermanent( "/NewURL.aspx" ); Check this article : http://www.c-sharpcorner.com/UploadFile/ashish_2008/1106/

ASP.NET 4.0 introduces some SEO improvements. Response has now new method called RedirectPermanent() . This method performs same redirect as Response.Redirect() but it uses response code 301. You can find more information about HTTP response codes from HTTP 1.1 specification, chapter 10. Status Code Definitions . Response.Redirect() returns 302 to browser meaning that asked resource is temporarily moved to other location. Permanent redirect means that browser gets 301 as response from server. In this case browser doesn't ask the same resource from old URL anymore – it uses URL given by Location header. To illustrate difference between Response.Redirect() and Response.RedirectPermanent() let's look at simple example. We need one usual ASP.NET Web Application with Global.asax file. In Global.asax file we have to implement BeginRequest() method. protected void Application_BeginRequest( object sender, EventArgs e) { if (Request.FilePath == "/our-products.aspx" ) { Response.Redirect( "/products.aspx" , true ); } if (Request.FilePath == "/about-us.aspx" ) { Response.RedirectPermanent( "/about.aspx" , true ); } }
