Rails - May 2009 - How can I read a cookie set on another subdomain by a non-Rails app?

I''m trying to build some single sign on functionality into our web
application.

There''s community site on a subdomain:  i.e.  community.domain.com

The Rails app is on:  www.domain.com

When I inspect the cookies, I don''t see any of the
"community.domain.com" cookies.

In "production.rb", I have this:
ActionController::CgiRequest::DEFAULT_SESSION_OPTIONS.update
(:session_domain => ''.domain.com'')

That doesn''t seem to help.

How can I get my "www" app to read from the "community"
subdomain?

Thanks,
Andy

what is the app setting the cookies doing ? if it''s setting them for
community.domain.com rather than .domain.com then you can''t get them
because the browser won''t be sending them

I have no control over what the "community.domain.com" server does.
It''s a hosted application.

So you''re saying that the browser won''t be sending cookies
from
"community.domain.com" for use on other subdomains?

Thanks,
Andy

correct (see http://tools.ietf.org/html/rfc2965 ) (unless the
subdomain was something.community.domain.com)
