cross-subdomain sessions

[Anon]

Alright, I'm not sure if this is right, but let me set out the situation for you:

I have two machines, let's say demo1.foo.com and demo2.foo.com. Now, these two are on two different IP addresses. When they go to demo1.foo.com, they log in and the information is set in a session.

Now, I was told that since both of these machines are in the ".foo.com" domain, then you could just set the domain for the session to ".foo.com" and be able to use the same login session over on demo2.foo.com.

So far, I haven't gotten it to work properly. Is there anyone out there that has been able to get this done? If so, got some code I could mooch? 🙂

Thanks,

You can set the session-id cookie manually, and thus change the domain for which it is set.

have a look at the setcookie function and the annotations in the manual.
