[mod_python] Global variable...

I've achieved a similar thing by creating a Globals module. This is imported
by all modules that require any global variable. I'm also using this module
to store a dictionary of users as well as other cached content. It seems to
work effectively for me. Anyone aware of any problems with this approach?

Thanks

   HI.

   You must use shared memory for that. The shmmodule can help you (look
for it on Vault of Parnassus).
   I  have written a trivial class to save and restore objects in the
shared memory. You can download it from:

   http://www.sj.univali.br/~sobral/persist.tgz

   It has been used to implement a cache for logins and passwords, used by
a PythonAuthenHandler. The cache is a dictionary, which lives in the
sahred memory.

   It has some comments to help you to use it.

   Best regards.
