翻译强力驱动I have multiple subdomains and i'm trying to use the sessions across subdomains.
http://example.com http://subdomain.example.comI have also set the cookie domain in config.php
$config['cookie_domain'] = ".example.com";The session userdata and also flashdata are empty when used in the other domain. Im using the same session table as well for both CI instance
From the following solution : Sharing sessions
Both the cookie_domain and cookie prefix has to be set
$config['cookie_domain'] = ".example.com"; $config['cookie_prefix'] = "example_";first floor is right ,but does not clearly the reason

CI’s session, like any other session mechanism, uses a cookie to identify the session. It’s is the cookie that should be available cross-domain.
For domain, you need to specify ‘.domain.com’, not ‘*.domain.com’.
Only $config['cookie_domain'] part is required, $config['cookie_prefix'] is only to make things clean or you have some sub domain uses same domain but does not wanted to be shared.
