Dear list, I have the following sample: \setupinteraction[state=start] \starttext \insertpages [https://eur-lex.europa.eu/legal-content/EL/TXT% /PDF/?uri=CELEX:32015D0022] [width=0pt] \attachment[file=https://eur-lex.europa.eu/% legal-content/EL/TXT/PDF/?uri=CELEX:32015D0022] \attachment[https://eur-lex.europa.eu/legal-content/% EL/TXT/PDF/?uri=CELEX:32015D0022] \stoptext The docuemnt may be attached to the PDF document, but pages cannot be inserted to generate a booklet. Attachment doesn’t work either when the "file" key is removed (see second one. Would it be possible that \insertpages and \filterpages could deal with these urls? Or what am I missing here? Many thanks for your help, Pablo -- http://www.ousia.tk
