[webkit-dev] FrameLoaderClient notifications

[Artem Ananiev]

Hi, Patrick,

in Java port we do the same: store Frame* in FrameLoaderClient. However, 
this frame's loader URL can't be used, for example, in 
postProgressStartedNotification as it contains the current URL, not the 
URL which is about to be loaded...

Thanks,

Artem
