In order for the bean to exist between client requests, the client
must have cookies enabled in their browser. A cookie called
JSESSIONID is how the servlet container tracks a user session.
If the cookie doesn't get sent with the clients request, the clients
session can't be found, so the bean is recreated instead of reused.
