Multiple Domain Sessions

Access a SESSION array created on www.mydomain.com via sub.mydomain.com?

[Sekka]

Hey.

I have a website located at www.mydomain.com. I have a sub-domain located at sub.mydomain.com and I want it to be able to access a SESSION array set by www.mydomain.com within the sub-domain. My server won't allow this as they are different domains, therefore, different sessions.

Can I set my server to allow both domains to access the same SESSION? If not, what is the best way to pass it over? POST?

Thanks

Note: I am running a dedicated server with Lunix and Plesk incase I need to change anything. :)

i think that might work if you went by the IP address and not the domain name, but don't quote me on that, I have enough session cookie worries of my own.

You dont by any chance use dreamweaver?
i created a session cookie on a page which updates a record and goes to the next page, but you cant access the session from there on - it works fine when there is no update query involved..

I'm not sure if this is possible, but can you pass the PHP SESSION ID via POST and set the session on the sub-domain to the passed session?

Ok, this is kind of what I am talking about.

Except, how can I make it so a SESSION is set and used in the main domain and the subdomain aswell?

Thank you!

Sekka,

I use the following method which works for my sites.

session_set_cookie_params(0 , '/', '.example.com');
session_start();

The .example.com means it will work for anything ending in example.com

don't forget the . before the domain name though!

Why is the "." so important out of interest?

[proper_bo]

if you used example.com it would mean ONLY example.com

.example.com means example.com AND any subdomain there of
