You can replace docShell.notificationCallbacks with your own 
implementation of nsIChannelEventSink.  Then your implementation will 
receive onChannelRedirect calls that pass both the old and the new channels.

Just make sure to delegate to the original object when 
notificationCallbacks gets QIed to any other interface, since it 
implements a number of important ones.  You should probably also call 
the onChannelRedirect method of the original object as well after your 
implementation is done doing whatever it needs to do.
