This demo performs simple session handling. No login is required so you can use this to manage session data for guest users as well as users with a Google account. The basic flow here is:
Generate a session key for each new visitor.
Store session key in a cookie named "short-cookie".
Use the session key to load/store some user-specific data using the AppEngine memcache.
For this demo, both the cookie and session data are set to expire in 60 seconds so you can see what happens.
