Anything that's got a bool return value probably should be named different from
Notify. You don't have to fix the other ones (unless you're really nice!) but
can you rename this? To avoid the naming conflict with the virtual private
member functions, I'd name them FooInternal() or something.

Done.  I renamed the cookie related ones too. (Renaming is easy in Eclipse, when
it works.)
