ASP.Net Response.Redirect Vs Server.Transfer

Basically, Response.Redirect is let the internet browser request another page.
This function often uses for the user re-direction to a register page or the wrong page.
Because the re-directional is compulsion requested the new page,
it will bring the browser must arrive the Web server - two times,
and also the Web server will multiprocessing request.

IIS 5.0 has introduced a new function Server.Transfer,
it will carry out shifts to another ASP page on the same server.
this will avoids the unnecessary round-trip between internet browser - Web-server,
thus improved the overall system performance as well as reduced user's response time.
