Server.Transfer is one of the great new commands you can
use if you've got ASP 3.0. It allows you to move
processing to another ASP page to fulfill a client request.
It's much more efficient and eliminates the redirect
command being sent to the browser and the browser needing
to make another request that occurs with Response.Redirect.
There is one little catch however...
Since the client was never told they were moved, you need
to be careful when using relative links. If you've moved the
client to a directory different from where they started, you
need to be sure the document you redirected them to can still
find any support files it needs. This usually shows up as
broken images on the client and while it can easily be fixed
by using absolute paths in the target file, it can easily
catch you off guard if you're transitioning from
Response.Redirect commands and were't expecting it.
