//应用页面:
/*
//设置 cookie
document.domain = "qq.com";
var expires = new Date();
expires.setTime(new Date ().getTime() + 1800000);//半小时
Cookie.setCookie("autoapp_test","111111111",expires,"\/cookie","qq.com");


//获取cookie
var cf = new FCookieFrame("test","http://auto.qq.com/cookie/cookie.shtml",function(){
    //alert("load finished");
    alert(cf.getCookie("autoapp_test"));
});

功能:支持在根path下(/) 获取子path下的cookie (/cookie)
