The the FrameLoaderClient functions about the frame (not the ones that  
take DocumentLoader*) are what you want. They are all about this  
cycle. dispatchDidStartProvisionalLoad is the one that goes first, and  
then there are quite a few others, ending with dispatchDidFinishLoad,  
dispatchDidFailLoad or dispatchDidFailProvisionalLoad.

All loads start provisional.

There is
dispatchDidReceiveServerRedirectForProvisionalLoad for loads of the  
main resource of a frame, but dispatchWillSendRequest alone is all  
that's needed for arbitrary resource loads.

assignIdentifierToInitialRequest and dispatchWillSendRequest
