Also note that in mod_python 3.x "req.send_http_header()" is not required, and is in fact a noop. To get a better feeling for the difference between SetHandler and AddHandler I'd suggest using the same handler in each of your .htaccess files. Try accessing a couple of different files (.py, .txt, .html) using both setups and you'll get a pretty good idea of the difference between the 2 directives. Jim
