Service to detect 3rd-party cookies support.
Running on heroku spooky-cookie.herokuapp.com, http and https.
Page's head should have http/https detection script <script src="https://spooky-cookie.herokuapp.com"> </script>. Callback function should be defined function spookyCookie(areSupported) {..} - will receive true if 3rd party cookies are supported
Code injectes a feature-detection script and callback function what sets a feature-class like modernizer.
(function detect(){
var spookyCookieService = "spooky-cookie.herokuapp.com";
window.spookyCookie = function(gotCookie){
gotCookie && $('html').addClass('cookie-3rd-support');
/* or your code */
};
var script = document.createElement('script');
script.src = (('https:' == document.location.protocol) ? "https://" : "http://") + spookyCookieService;
var head = document.getElementsByTagName('head')[0];
head.appendChild(script);
})();
