... показал, что веб-сервер static.prian.ru разрывает соединение, если в запросе нет поля User-Agent.

Т.е. такой код работает прекрасно:

@main[]
  ^use[/../../hydra-vts.beta/classes/pf/io/pfCFile.p]
  $f[^pfCFile:load[binary;http://static.prian.ru/uploads/2012_06/12/201206120314501400429848.jpg;
    $.verbose(true)
    $.stderr[curl.log]
    $.user-agent[Parser 3]
  ]]
  ^f.save[binary;t.jpg]

curl.log
