Python, WSGI, multiprocessing and shared data

Question

I am a bit confused about multiproessing feature of mod_wsgi and about a general design of WSGI applications that would be executed on WSGI servers with multiprocessing ability.

Answer 1

If you are using multiprocessing, there are multiple ways to share data between processes. Values and Arrays only work if processes have a parent/child relation (they are shared by inheriting). If that is not the case, use a Manager and Proxy objects.
