				if (c) {
   
					var r = new Date;
					r.setTime(r.getTime() + 36e5 * c)
				}
				return document.cookie = e + "=" + escape(t) + "; " + (c ? "expires=" + r.toGMTString() + "; " : "") + (i ? "path=" + i + "; " : "path=/; ") + (n ? "domain=" + n + ";" : "domain=" + o.DCCookieDomain + ";"), !0
			},
			get: function(e) {
   
				var t;
				return function(e) {
   
					if (!e) return e;
					for (; e != unescape(e);) e = unescape(e);
					for (var t = ["<", ">", "'"
