[NTG-context] Cross-reference to PDF via web

Good evening. Is it possible to acces a inter-file cross-reference via web? I have some documents for my students, all created with ConTeXt. Each chapter in each document has a cross-reference. I can access one document from another via web like this: \goto{here}[URL(http://www.econ.muni.cz/\~qasar/vyuka/barro/barrografy.pdf)] Is it possible to go to some specific chapter? I tried \goto{here}[URL(http://www.econ.muni.cz/\~qasar/vyuka/barro/barrografy.pdf)::chap:somechpater] but it didn't worked. Is it possible to do it somehow? Many thanks for your answers. M.K.
