If the given url path didn't match a function, it is passed to this function
for further handling. By default, it throws a NoSuchFunctionException.
Overriding it might be useful if you want to serve generic filenames or an opDispatch kind of thing.
(opDispatch itself won't work because it's name argument needs to be known at compile time!)
Note that you can return Documents here as they implement
the FileResource interface too.
