What is the difference between Response.Redirect() and Server.Transfer()?

Server.Transfer is give better result than response.redirect
in Server.Transfer, it occures on serverside so it give fast performance than response becouse response is work on two network trip like client side and server side
In server.Transfer()
client makes request
server receives request
server transfers to different page (all done on the server)
new page is rendered and sent to client
In Response.Redirect()
client makes request
server receives request
server response to client with a redirect.
client receives redirect
client makes new (2nd) request
server receives request
 new page is rendered and sent to client
so response is done in two networktrip
