Javascript Question

setting cross-subdomain cookie with javascript

How should I add domain support to these functions? I want to achieve that .example.com is declared as domain, so that the cookies can be read across all subdomains of the example.com. In its current form since domain is not set, it can only be read from www.example.com

Answer

Here is a link on how to share cookies amongst a domain:

http://javascript.about.com/library/blwcookie.htm

It involves setting the domain attribute of the cookie string like:

document.cookie = "myValue=5;path=/;domain=example.com";

This cookie should now be accessible to all sub domains of example.com like login.example.com
