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?
context.Response.Redirect(ConfigurationManager.AppSettings["URL"] + ext );
You can't is the short answer. The browser is the only thing that can open up a new window.
response.write("<script>"); response.write("window.open('page.html','_blank')"); response.write("</script>");
