validate - keepalive ajax call

[mhenke]

Is there a way to validate the keepalive response?

Case: Multiple tabs.

• Tab 1 logs out automatcially with sessionTimeout.js
• Tab 2 person keeps pressing stay connected
  • user thinks they are still logged in but really aren't

Ideally, maybe stayalive would return text like "Ok" or a status code that would be validated.
