Sessions across subdomains

[Netpepper]

Hi,

I am trying to get Sessions passed through to different subdomains. I have tried about everything I could find on the internet, but absolutely nothing seems to work...

What I need is to check if a user is logged in on various subdomains. So, if the user logs in via sub1.domain.co.za, he should still be logged in when he opens sub2.domain.co.za or www.domain.co.za, or vice versa.

I have tried to "tell" the system in various ways that the session is valid for the entire ".domain.co.za" range, just as I would do for cookies. With actual cookies, I have no problems at all, but with sessions it just does not want to work. I have tried these methods for registering the session:

[code]ini_set("session.cookie_domain", ".domain.co.za");
session_start();
$_SESSION["test"] = "this is a test";[/code]

and

[code]session_set_cookie_params(time() + 3600,"",".domain.co.za");
session_start();
$_SESSION["test"] = "this is a test";[/code]

I have also tried the session_register() function. This does initialise the session and register the variable "test", however, if I try to access the session data from a different subdomain with:

[code]session_start();
echo $_SESSION["test"];[/code]

no value is returned. Even if I use ini_set("session.cookie_domain", ... ) or session_set_cookie_params() and set the session domain to ".domain.co.za" once again, I cannot retrieve the value for the previously set variable "test". Instead, a new session is started. If I leave session_start() out, no session is available at all.

I am sure that I'm doing something wrong, but what???

My PHP version is 4.4.2, standard setting for session.cookie_domain is NULL, Apache version 1.3.36

Please help me!

As far as im aware it is impossible to carry sessions over to another domain. That could cause all kind of problems for people if you think about it.

Thanks. Would it be impossible even if it concerns subdomains within the same domain? Then what is the purpose of the "domain" setting for Sessions in PHP, I wonder? [img src=\"style_emoticons/[#EMO_DIR#]/huh.gif\" style=\"vertical-align:middle\" emoid=\":huh:\" border=\"0\" alt=\"huh.gif\" /]

I dont know as im not expert in sessions varibles. But the only was i could see it working is if the domains route was in the same place??

That's the thing; the subdomains are hosted on the same server; they are in different subfolders of the main folder (public_html). Therefore, I do not understand why it is not working...
