Response.Redirect sends a Response to the Client browser, which tells it to
request another page. Yes, this does mean that the server will receive 2
requests from the client, whereas Server.Transfer transfers control to
another class without redirecting. However, there are reasons for both
methods to exist. Only Response.Redirect will ensure that a Refresh from the
browser will not cause the last PostBack to re-occur. It's not like the 2
are interchangeable. When you need to hammer nails, use a hammer, not a
screwdriver.
