It is client side. The only thing the server does is tell the client
that it needs to the redirect to a different location. The client is
generally smart enough to handle this without you a page refresh, but
this does not diminish the fact that the client does 99% of the work.
The client could just sit there and say it couldn't understand what
all this redirect stuff means.
Anyhow, regardless of what we thing is and isn't a client-side
redirect, using <cflocation> (http response code 307) is a client side
redirect and using getPageContext().forward() is a server-side
redirect. Get over it and move on.
