site-wide cookies and subdomains issue

[eluser]foetus[/eluser]
Hi,

I know there's a lot of post already with similar issues, but I haven't found anything that solve my problem yet.

so here is my problem:

I know that if I want cookies to be valid for all my subdomains I need to do this:

Code:

$config['cookie_domain']    = ".domain.com";

but the problem is that even after doing that, I still get domain.com as the cookie domain, so I get logged out when I move across domains. (domain.com, sub1.domain.com, etc).

So, what Am I doing wrong?

well, it seems that the problem is not codeigniter, I tried setting up the domain parameter manually and it still doesn't work.

I'm using a wild card, with modrewrite to simulate sub domains, so maybe this could be causing the problem. not sure tough...

I'm replying just to not leave this problem open, and maybe to help others xD (you never know ).

so far, after several test, this is the conclusion I have come to:

for some reason browsers, seems to ignore cross-domain cookies for the domain I'm using: domain.do (.do it's a new domain for Dominican Republic). Chrome doesn't seems to be acepting cookies at all!!, at the start it wasn't even recognizing the domain name :S

I'm saying this because I tried running the same script on the same server, using 2 domains: 1 .com, 1 .do, and the result for the .com domain was successful (.domain.com), but for the .do domain, for some reason it goes converted to: domain.do (without the . at the beginig).

when I see the Http response using firebug for example, I do see: .domain.do, but on the cookies plugin (firecookie) I just see the domain, and the cookie doesn't work for the sub domains.

everything works ok on IE 9

It basically can not work. A IE9 save the same cookies on domain.com and domain.do. Delete cookies and try again. If server 1 you can try to make the emulation of cookies in a text file. <a href="http://www.frcoupon.com">My help.</a>

I'm not using 2 domains for the same application, I'm just using domain.do, and some subdomains, like: sub1.domain.do, sub2.domain.do.

I used the .com domain, just to make a test on the server, it has nothing to do with domain.do
