Hi, I have Plesk 9.3 on a new server. I have a domian (domin.com) setup and a subdomain (sub.domain.com) setup as another domain rather than as a subdomain of the original. This allows me to specify a separate IP address for the subdomain and use 2 SSL certificates, one for the domain, one for the sub domain. I am unable to use the sub.domain.com sookie to verify a session from domain.com Both domains are hosted on the same server and write their files to the same place. I have tried chmod 777 the session files because the domains are controlled by a different user due to Plesk restrictions but this doesn't help. I have also tried setting the session domain in php.ini as .domain.com but this also doesn;t help. Anything else I can try ?
