In Revolution, by setting session_cookie_domain to .example.com -- in Evolution I’m not sure this is possible without editing the PHP configuration and changing the session.cookie_domain ini setting.
How can i make sessions work across subdomains of my modx site?
The site is multilingual and each language is on a different subdomain eg en.example.com, de.example.com ect..
How can i configure the setup to be able to read all sessions across all subdomains?
