Why do you keep mentioning mod_php, surely you mean mod_python.

I wouldn't rely on it being exactly the same. The way it works uses a
number of kludges. Also, the mod_python.cgihandler code in mod_python
doesn't really get much attention from mod_python developers anymore
and not sure if it was even specifically retested when mod_python 3.3
was released.

Have no idea why it doesn't work as works as written on MacOS X even
when mod_python.cgihandler is used.

You'll have to get someone else who has Windows to try it. You might
be better off going to the mod_python mailing list to get help, or
just use plain old CGI instead since using mod_python isn't really
going to gain you much anyway.
