Version 3.1.4 of mod_python has various bugs in it which have been
fixed in 3.3.1, so upgrading would be a good idea anyway. Just make
sure you test your code on 3.3.1 before hand and specifically take not
of any issues with finding Python modules as module importer has
changed in a few subtle ways. See description of
apache.import_module() in:


Also, how your configure Apache 2.2 for authentication is a bit
different if you are using features such as Basic auth, so watch out
for that as well as that trips up some people, especially if they are
running their own custom mod_python authenhandler.
