// CUSTOM SESSION SAVE HANDLER CLASS EXAMPLE

// Uncomment & edit it if the application you want to integrate with, have
// its own session save handler. It's not even needed to save instances of
// this class in variables. Just add a row:
// new SessionSaveHandler();
// and your handler will rule the sessions ;-)
