session过期的问题
session问题，就是我session的过期时间4个小时， 设置cookie只要浏览器不关闭就能发送session_id, 现在的问题是我登录后什么也做（比如过半个小时），然后在操作的时候会让我重新登录
php设置
session.cookie_lifetime = 0
session.gc_maxlifetime = 7200

php设置
session.cookie_lifetime = 0
session.gc_maxlifetime = 7200
session.use_cookies是否为1
试试用session_save_path()函数，设定这个session的专用目录
