Ankit working with Rails interesting thoughts for ruby and rails development

In rails application if you want any browser session then you can get it by,

browser_token = (session[:_csrf_token] ||= ActiveSupport::SecureRandom.base64(32))

this token is changed every time when you restarts the browser.

If anyone knows any other way to get browser session in rails then please comment on this.
It will be appreciated.

Thanks
