Thanks for the reply.

The use case is that my client wants to block a range of IP addresses
from being able to view their site. So I need to access the
originating IP address and filter appropriately.

I've written a few custom zope products before, but I've not done
anything that really modifies zope's behaviour on every request - just
on requests for the specific objects I'm publishing. So I'm familiar
with the request object, but I don't know how to intercept *every*
request. Are there any global request life-cycle hooks? If you can
point me to those that would be a great help.

Cheers,
David
