Cookie Domain Issue

[Deo]

Hi,

Well i have kinda a small issue that I cant quite figure out. Heres my problem:

I need to access information via a couple cookies on website X, while the cookies are being set on website Y using a setcookie function.

When I attempt to create a cookie on website 'ydomain.com' by doing:

setcookie("id", '1234', time()+(60*60*24*365), "/", '.xdomain.com', 0); 

the cookie doesnt get set. Is there a way I can set and allow other domain's to read the cookies?

Thanks!

Cookies, as far as I know, can only be created and accessed by the domain itself, not any other domain. If I were able to access cookies from other websites, it would create a huge security hole as I would be able to retrieve any password information stored in the cookies.

Well, php.net documentation talks breifly about allowing sites access to cookies, but I havent been able to find out how to allow access to another domain as of yet.

Thought someone might know.

Anyone else have any experience?

As pointed out, you can't access cookies from different domains. The most you can do is read/write the same cookie in the same domain, no matter what subdomain and path are: *.domain.com/*
