Do you support POSTs for fetching dynamic data? I found where it's pulling from, here's the curl command:
curl "https://www.keepandshare.com/calendar/fns_asynch_api.php?r=0... --data "action=getrange&i=1940971&from=2013-12-26&to=2014-02-06"
curl "https://www.keepandshare.com/calendar/fns_asynch_api.php?r=0... --data "action=getrange&i=1940971&from=2013-12-26&to=2014-02-06"
