Problem with session_id when going

HI, I have a problem. I
I have a site that is not secured and I create a session id that I track user. When customer goes to secure site to enter his info his session id is lost. What can I do to preserve the session id when customer moves from non-secure to secure version on my site.

The problem is where does php stores it's session_id. in which folder. I think that I need to find where php stores session_id on my server for non secure site. And then I should point my secure site for php to look for session_id in non secure folder.

Can some on tell am I right. Also where does php stores session_id on my server. Does it store seperatly session_id for each website or in just one place on my server.

Please advice.

THank you

You might wonder how can I tell all this? Just because your message is off-topic here and it first tells me to find duplicate posts in other forums.
