When I start a session in one of those, that session is only valid in that session. How do I make the session valid for the entire "mydomain.com" domain?? so that variables in the session are available in all subdomains?
problem should be solved when the cookie, wich the session automaticly sets, appears in every subdomain.
so if I start a session in sub1.domain.com and then go to sub2.domain.com the cookie set by the first session appears there.
