cookies.js

function getCookie(name) {
	var cname = name + "=";
	var ca = document.cookie.split(';');
	for (var i = 0; i < ca.length; i++) {
		var c = ca[i];
		while (c.charAt(0) == ' ')
			c = c.substring(1);
		if (c.indexOf(cname) == 0)
			return c.substring(cname.length, c.length);
	}
	return "";

function setCookie(name, value, days) {
	var t = new Date();
