I have a problem sharing the session between two subdomains, and I've read a lot of threads here and other places.
I have www.xx.com and sub.xx.com and I've set
session_name("PHPSESSXX");
session_set_cookie_params(0, '/', '.xx.com');
and the session.save_path is the same on both domains.
I get a cookie called PHPSESSXX on both domains, and it has the same value.
When I log on to www.xx.com I get a session with some details in it, and it stays that way until I go to sub.xx.com. Then the session on sub.xx.com is empty, and if I refresh www.xx.com, the session there is gone as well. So it does something, but it seems to be overwriting the session data each time I visit a different subdomain.
Any ideas anyone? - Can i debug this somehow?
Btw: I'm using ssl on both domains.
cheers
