WWW and non-WWW URL. Two different sites?

Question

I am noticing that my sites session cookies are different between the two. If someone logs in on the www.mysite.com they are not logged in on the non www site. How can I fix this?

Answer 1

为Cookie添加域，如下所示：

cookies[:key] = {:value=>val,:domain=>'.mysite.com'}

Answer 2

在config/initializers/session_store.rb , :domain => ".yourdomain.com"在Application.config.session_store行的末尾添加, :domain => ".yourdomain.com" 。
