How to set default cookie domain in Rails3

rubyonrails-talk
1

I want to set default cookie domain for my application to ".mydomain.com" to allow cookie session be preserved across subdomains. I use => config.action_dispatch.session = {:domain => ".mydomain.com"} in application.rb, but thats not working. The cookie is saved as 'mydomain.com'

Thanks for the help!

Try: Rails.application.config.session_store :cookie_store,                                   :key => '_app_session',                                   :domain => '.mydomain.com'
