I think your options are: - Make the object pickleable <https://docs.python.org/2/library/pickle.html#pickling-and-unpickling-extension-types> and store it in the session (this is only necessary if you really need a separate object for each user's session). - Store the object in cache.ram (you can use a key for each user if you need multiple objects, but remember to clear old keys periodically or RAM will fill up). - Create a singleton or, if necessary, a "multiton" (keyed registry of singletons -- e.g., http://stackoverflow.com/a/7493603/440323).
