Prevents myPOS from redirecting you out of their dashboard
Simple script to prompt when the myPOS dashboard tries to log you out, in order to prevent automatic redirect. If you miss their popup asking you to extend your session, just press the Stay button of the browser prompt, and then press their extend button. The dashboard won't try to redirect you anymore, since it thinks you're already logged out. There is a server-side session timeout too, every 30 seconds the script tries its best to extend it, by requesting a dummy page (transaction list).
