What you want is automayic module reloading.

Have a look at the automatic module reloading mechanism implicit
within the apache.import_module() function. See documentation at:


This same method is used by mod_python to load a handler. In that
case auto reloading is controlled by the PythonAutoReload directive.


The current auto reloading mechanism has a number of shortcomings
and will not always work, but depending on the complexity of your
code it may be sufficient.
