When _publisher.py is this:

from mod_python import publisher, apache
from os.path import basename

def handler(req):
   req.add_output_filter('DEFLATE')
   req.write("""
      req.filename: %s
      req.uri: %s
      req.path_info: %s
      req.args: %s
      """ % (req.filename, req.uri, req.path_info, req.args)
   )
   if basename(req.filename) == 'index.py':
      req.uri = '/'
   req.write('basename: "%s" req.uri: "%s"' % (basename(req.filename), req.uri))
   return apache.OK
   return publisher.handler(req)

calling it like this:
http://example.com/carro/Fiat/DF/Sao_Paulo/2

I get this:

      req.filename: /var/www/html/example.com/index.py
      req.uri: /carro/Fiat/DF/Sao_Paulo/2
      req.path_info:
      req.args:
marca=Fiat&modelo=&uf=DF&localidade=Sao_Paulo&bairro=&tv=carro&pagina=2
      basename: "index.py" req.uri: "/"

I will write it to the log later. I'm leaving now.
