donottrack.js
// Respect do not track for all browsers. Except for IE 10 and 11 where we ignore it
var dnt_isIe10or11 = (navigator.appVersion.indexOf("MSIE 10") !== -1) || (navigator.userAgent.indexOf("Trident") !== -1 && navigator. userAgent.indexOf("rv:11") !== -1);
var DNT = (navigator.doNotTrack || navigator.msDoNotTrack || window.doNotTrack);
DNT = !DNT || DNT == "unspecified" || DNT == "0" ? false : true;
if (!DNT || dnt_isIe10or11) {
var gaJsHost = (("https:" == document.location.protocol) ? "https://ssl." : "http://www.");
// GA loading code
