Using Cookies to Set Object State

We needed to find a way to store user activity across sessions independent of the LMS platform for a particular course by utilizing the setting and getting of cookies to set the particular course completion state to True, and then reading it back and setting a variable that would be used to change the object state.

Here is the setter:

document.cookie = "Course1="+escape("True")+ "; expires=02/02/2013 00:00:00";

And here is the getter:

function get_cookie ( cookie_name )

{

  var results = document.cookie.match ( '(^| ?' + cookie_name + '=([^;]*)(;|$)' );

  if ( results )

    return ( unescape ( results[2] ) );

  else

    return null;

}

var courseStatus = get_cookie ( "Course1" );

var player = GetPlayer();

player.SetVar("Course1",courseStatus);

Of course, it's not working. Any suggestions on the best approach, or if this is even feasible?
