Session Redis更改每个新的重新加载Web浏览器

I have a website with php & nginx. My website uses Symfony 1.4 . My session is stored on Redis. I have got stuck with session redis . Every I reload (f5) or open new page then I see that my session value is changed.

Here is my configs for the website:

1/ Redis session storage: session.save_handler = redis session.save_path = "tcp://10.30.3.15:8875?prefix=PHPREDIS_SESSION_MYSITE:" 2/ My config session in factories

storage:
    class: sfSessionStorage
    param:
        session_name: mysession
        session_cookie_path: /
        session_cookie_lifetime: 2592000 
        session_cookie_httponly: true
        session_cookie_secure: false

I write a funtion so that all member must redirect to login page when accessing my website without logging in before.

My website use HAPROXY for load balancing.

My problem are to be changed session value in cookie firebug and some time I was be logout ( redirect to login page).

Please help me fix this problem.

Thanks & Best regards,

David Abbala.
