Retrieving all subdomaines/superdomains cookies from with subdomain using javascript

Question

I am getting partial list of cookies with document.cookie when executing on subdomain. I would like to retrieve superdomain+subdomain cookies. Is there any way to do that?

Let say I have a domain

example.com
sub.example.com

And I have cookies set

name=value domain

c1=2 => .example.com
c2=4 => sub.example.com

If url in browser is sub.example.com I want to get all the above cookies how would I do that? document.cookie only returns c2=4

You are trying to access cookies from different domain. Browser not going to allow this. Please refer this.

Turns out there was a flag in browser which sets httponly cookie, This cookie is not visible from document.cookie javascript method for security reasons.
