[Zope] blacklisting referers and/or specific hosts

[Tim Hicks]

Hi,

I have a zope site up and running which has recently had a *lots* of hits
from a client (or clients) that show referers pointing at various
gambling, meds, and loan sites.  Requests only come in for the main page,
not for the associated images, css, etc that should go with it.

The consequence is that my server is working harder to service a client
that isn't interested in what it has to say, and my Z2.log is now far less
useful to me as all these bogus requests drown out most of the useful
information.

So, I'm wondering if there's a way to blacklist those clients that I don't
like based on host/ip and/or on referer.

If I hook into the traversal process in the same way as the virtual host
monster objects do, could I check the request against my blacklist and
then do a REQUEST.close()?  Would that still appear in my logs?  Does that
even make sense?  Is there a HTTP response code that I could return to
these clients that would stop them being interested in my server?

Any ideas much appreciated.

Tim
