session有关问题请问

com cookie session start

session问题请教
第一个页面写入session了
$_SESSION['uid']=$rows['uid'];
$_SESSION['uname']=$rows['uname'];
$_SESSION['rname']=$r_rows['rname'];
现在有个问题是跳转到其他一个页面session打开之后里面没有值,麻烦大家解决下

------解决方案--------------------
代码怎么写的? 有没有开启session_start();
------解决方案--------------------
两个页面都需要对SESSION操作前调用 session_start()
你确定做到了吗?
------解决方案--------------------
1,session_start
2,是否session_set_cookie_params设置过cookie的domain为.xxx.com

第二点比较重要,因为比如我的网站叫做www.aa.com,我在浏览器用aa.com访问,结果session失效,为什么?
因为session_start默认以当前访问的URL作为cookie的domain,结果www.aa.com访问时得到一个session-cookie,访问aa.com得到另一个session-cookie,my god。
