ASP.NET supports two major ways to redirect users to a new page programmatically: using Response.Redirect and Server.Transfer. Since both behave pretty differently, the following two sections describe their behavior in more detail.

7.3.1. Programmatically Redirecting the Client to a Different Page

Within each ASPX page you have access to a property called Response that you saw earlier when saving the cookie for the selected theme. The Response object gives you access to useful properties and methods that are all related to the response from the server to the user's browser. One of those methods is the Redirect method.
