Is there a way to get access to a cookie stored a root site in a session set at subdomain level

being at root level http://mydomain.com, I stored a cookie
cookie[:login]
I can see the cookie in my browser
site: mydomain.cm
login
_myapp_session

upon redirection, to url => http://test.mydomain.com ,
I would like to access this cookie, cookie[;login], but as I maintain
sessions at subdomain level, I have
site: test_domain.com
_myapp_session

how can I access the cookie[:login] ?

thanks for any clue …

I tried to use the :domain

cookies[:login] = { :value => 1, :domain =>“test.mydomain.com”, :expires
=>
1.hour.from_now }
but no way cookies is not set for test

should I rather use ?
cookies[:login] = { :value => 1, :domain =>“.mydomain.com”, :expires =>
1.hour.from_now }
