Can you just pass the URL to the file, and not pass it through send_file? I've used

def download
if cannot?( :download, Title )
raise CanCan::AccessDenied
else
redirect_to @asset.source.expiring_url(10)
end
end

from Paperclip to handle a link to a protected file on S3. Works like a charm, and it's just a file download from S3, so it's up to the browser to handle that.
