Also note that if the site_setup module is changed, it won't be automatically reloaded unless xmlhandler.py is also changed. Plus, if you have many site_setup.py in different directories, they will collide with each other. The dirt simple solution to the collision problem is simply to put site_setup.py in a separate directory (not one accessible from Apache), put the directory on the PYTHONPATH environment variable and simply use a standard "import site_setup" instruction. But then, your module won't be automagically reloaded when modified... Note that mod_python 3.1.x is purposedly quite low-level. It does not provide a high-level application framework, so things like data or code sharing between pages are not handled. You should either build your own framework or use one like Vampire (http://www.dscpl.com.au/projects/vampire/). Meanwhile, we are trying to provide a few more stepping stones in the upcoming 3.2.0 release.
