It's a whole lot more practical to just stop using mod_python and go for one of the other ways of exposing Python code to the internet. I bet you can get the same or better performance out of another solution anyway, and you'd save deployment headaches. -bob _______________________________________________ Python-Dev mailing list Python-Dev@python.org http://mail.python.org/mailman/listinfo/python-dev Unsubscribe: http://mail.python.org/mailman/options/python-dev/archive%40mail-archive.com
