Getting the PDF from that scheme might not end up being trivial.
Indeed. In this case it seems HEAD requests are blocked. I tried to fetch the direct link to the pdf with the HEAD script and it returned text/html and "Content-Disposition: filename=404.txt". So it's necessary here probably to use a GET request with LWP::UserAgent and from there read the http headers :-/
