File request should be ignored

My last URL looks (visitorpath_path()):

array
  'timestamp' => string '1286208909' (length=10)
  'title' => string 'Page not found' (length=14)
  'path' => string 'files/downloads/jpg/b915685bb98456b87580272c0fc0e0c1.jpg' (length=56)
  'referrer' => string 'http://doc/node/567' (length=19)
  'uid' => string '205' (length=3)
  'timeonpage' => int 9

Which is not true.
Any way to filter file request?
