I guess Python could do it without storing the session ID in a fi= le or database and instead in process state (i.e. application memory, right= ?), but the effect seems basically the same. Without being per-connection, = what is the value of process state? > Caches and stuff. For example, you might establish a database connection, and then hang onto it for all queries; or maybe you load up a bunch of user objects and keep them in memory for when you need them again. Anything that you store in a global (module-level) variable will hang around. ChrisA
