[Phplib-users] Multi-domain sessions?

[James S. <li...@br...>]

I posted on this a while back but hadn't really thought through what I 
wanted to do.

I have three sites which all share a single database and which I'd like 
to share a single shopping cart. The SSL certificate is only valid for 
one of the domains so I definitely need to be able to have that domain 
access carts started at either of the other sites. Two of the sites are 
on one server and the third is on another, along with the database.

I'm using session4.inc and I'm guessing the best way to handle this 
would be to send three cookies when the user first visits any of the 
sites, one from each domain, each containing the session ID. I would 
then get the same session ID when the user went to any of the sites 
during that browser session.

My initial attempt to do this involved hacking session4.inc so that if 
$cookie_domain is an array it sends a cookie from each domain listed but 
this doesn't appear to have worked. My sessions within one site have the 
same ID but when I move to either of the other sites I get a different 
ID.

Any ideas?

James.
