If you are getting a 403 forbidden error then you either haven't
configured Apache correctly such that the mod_python URL you are using
is a valid URL which can be accessed, that the specific URL is
matching some pattern elsewhere in Apache which is denied for some
reason, or, you have named your publisher handler with a leading
underscore, which are private and therefore forbidden.

You need to work out what is generating the 403, Apache or mod_python.
