Passing Session between subdomain to top domain

[kbc1]

Hi

I need to be able to pass a collection of session variables from my subdomain.mysite.com to mysite.com.

each time i try at the moment it destroys the session variables upon displaying the first page from mysite.com

is there a way around this?

When you make a link from subdomain.mysite.com to mysite.com, pass in a variable X which equals the session id. Then, do as the PHP manual suggests:

session_start() creates a session or resumes the current one based on the current session id that's being passed via a request, such as GET, POST, or a cookie.

Or change your PHP configuration to set "session.cookie_domain" to ".mysite.com" (note the leading period) so that the session cookies are applicable across the entire domain.
