Hi James,

The problem is the way you're passing the URL to http.get().  URI.path does
not include the query string, so the loop continues because a gsessionid is
not provided in the URL for any of the requests (ie a request for '
https://www.google.com/calendar/feeds/<account>' is made on each iteration)

Try using the URI.request_url() method to get the path + '?' + query string,
and you should be all set.

Cheers,

-Ryan
