Probably the easiest thing to do would be to make the
confirm branch 
send some javascript to the client for it to then go to the
resource to 
download. That way the confirm will complete, it'll go back
to the 
previous page, then fetch the resource to download.

Another approach would be to add a hidden iframe which has a
url of the 
resource as the confirm true branch.
