I do understand this, and that's why I think that the module defined in
/app/index.py should not be overwritten by the one defined in
/app/subdir/index.py. Maybe the namespace of the module defined by
/app/subdir/index.py should be created within the namespace of the module
defined by /app/index.py, so that the latter would inherit names from the
former ? It seems that the publisher load each .py file as modules based on
the filename only, hence the name collisions. If directories or URIs could
be taken into account, this collision problem would disappear.

Well, that's the first thing I tried a few month ago, but that's not the
case on my installation (Apache2 + mod_python running on Windows 2000 SP4).
Maybe this is due to the fact that I used the PythonPath directive ? I
defined it like this (in httpd.conf) :

LoadModule python_module python/mod_python.so
AddHandler mod_python .py .psp
PythonPath
"sys.path+['C:/apache/python/Lib','C:/apache/Subversion/python','C:/apache/t
rac']"
PythonHandler mod_python.publisher | .py
PythonHandler mod_python.psp | .psp
PythonDebug On

How can I benefit from the behaviour you describe while also declaring the
libraries I need on the Python path ?

Thanks for your help,
