How can I get the cookies from a subdomain?

Let's assume I'm on sub.example.org, how can I get the cookies of .example.org from there? If that's not possible, is there a workaround like an hack or whatever that redirects to .example.org and then stores the cookies?

The cookie was set as HttpOnly flag, and the browser made me not able to get the cookie for JavaScript.

A web page only has visibility to the cookie with the most specific domain that matches its URL.

So if both example.org and sub.example.org both have a cookie named mycookie, a web page in sub.example.org can only access the one in the subdomain. It hides the cookie in the example.org domain, and there's no way to access it.

But if there's only a cookie in example.org, it will be visible to both example.org and sub.example.org pages.

When creating a cookie, it defaults to the full domain of the page, but the code can specify a less specific domain. So if sub.example.org creates a cookie, it will default to domain=sub.example.org. But the code can override this by putting domain=.example.org in the cookie explicitly.

More details can be found in The Definitive Guide to Cookie Domains.
