Question
Sharing cookie info across mulptile domains using PHP
How can I share cookie information across 2 or more different domains? For example, when a user comes to mydomain.com I want to create a cookie for both mydomain.com as well as anotherdomain.com. Is this possible or is this prohibited by browsers?
Basically my second domain points to the first domain so the website is exactly the same but when someone is logged in on the first domain, they are'nt logged in when viewing the site using the second domain. How can I keep cookies for each domain in sync with each other?
My application is written using PHP 5.
I've tried using 2 different setcookie() calls, 1 for each domain but it only creates a cookie for the domain the user is viewing the site in and not the second.
Thanks for any help/ideas.

Hi Rok-Kralj
I'm just trying to think how your solution would work...
A user goes to the homepage of firstserver. When dealing with the request PHP will create a new session and then return the reponse, including the cookie information about the new session id.
Are you saying that the after creating the new session, the firstserver should then call file_get_contents('www.sec
which would then create a cookie on the second server? How does the cookie information regarding the secserver get returned to the user?
Here's a description of a hack.
1. when a user logs in, your code has to contact a central login server, and log that user into the "network" of sites. don't return a page yet.
2. the central log in server will return a global session id.
3. your code returns a page, and, on that page, put a bunch of images. in each image, set the SRC to a "remote log in" script on each of the network's servers. in each url, append the session id cookie. also set the user's cookie in this page.
4. each "remote log in" script called will contact the central log in server, to validate the session id. if the cookie validates, then set a set a cookie. also, each script should return it's graphic to the client, so it displays something. maybe it's a 1 pixel gif.
5. the global session id should be expired shortly after this transaction happens, to avoid session hijacks. the individual sessions are managed on each of the sites, not through the central log in server. there are other ways to make this more secure, too.
