[Rails] Sharing sessions between subdomains?

Wed Feb 8 11:39:01 GMT 2006

      Hello,

   I know how to share sessions between subdomains  in PHP. Can anyone please guide me as to how I can share sessions using  Ruby? Where can I set the value of domain for which the cookie is set?

    I would like for a user to login on the home page and then go to blog.home.com and not have to login again.

    Any guidance/pointers are appreciated.

    Thanks'
    Frank
