Can't you just increase the session timeout value to a large value? Say
12 hours?
Or (depending on what you are doing), change req.getSession(false) to
req.getSession(true) to allow creation of a new session if one does not
exist? If you must have 'false', you should probably have an error
check, too, just in case...
