Cookie Validity Time

I am using the plugin for two different options for people to view the content we want to be view-able only after being paid for:

1. One time view with the cookie validity time

2. Period Pass

The period pass works fine, the problem we are having is when checking the One Time view timeout, we set it for .01 (one minute) to test, there is no ajax style check if the cookie is still valid and therefore will not block the user from the content after the time allotted. However, the cookie validity does work if you refresh or close the browser window any time after the set 1 minute.

Is there a way to have ajax or soemthing check the cookie in the background and automatically remove the user from having access to the content?
