I do not necessarily have to use response.redirect, but that is what I had. I would like to open the selected link in a new window. How do I do that?

You can't is the short answer. The browser is the only thing that can open up a new window.
What you can do is send a chunk of html down the response that has a link with your url as an href, target="_blank" and a chunk of javascript onload of the form that fakes a click. If this doesn't work then use a window.open(url);
response.write("");
