Hi David, Multiple wsgi processes will exist as separate OS processes meaning no visibility of each other's variables.
If you restrict the process count to 1 and have multiple threads, then you could keep global state in that way (cross thread), BUT standard multithreaded progamming (locking etc...) applies or you will pay dearly with unexplained random bugs. Best advice I can give you after using these tools for a long time is to just use Redis. Redis is awesome and perfect for this kind of thing. Thanks!
