var store = function(days) {

			obj.addBehavior('#default#userData');
			var exp = new Date();
			exp.setDate(exp.getDate() + days)
			obj.expires = exp.toUTCString();

			document.body.appendChild(obj);

			this.name = location.hostname;
			this.obj = obj;
	} else {
		return

store.prototype = {
	set: function(name, val) {
		this.obj.load(this.name);
		this.obj.setAttribute(name, val);
		this.obj.save(this.name);
