Konqueror download handling

[Adrien BUSTANY]

Hi,
I continue to work on Konqueror's nepomuk features, and I'd like to save 
the origin url when a file is downloaded. That's already done if the 
file is downloaded via kget, but not if Konqueror uses the native 
"download manager" (ie KIO if I'm right). I'm not even sure that this is 
handled by konqueror, and not by KHTMLView, I have to find a way to be 
notified when a download finishes.
Does anyone have any clue about how I could do that ?

Best regards
