  # check both the incoming cookies and the outgoing cookies to see if 
  # the cookie we're looking for exists.
  c = (self.all_cookies[key.to_s] || self.all_cookies[key.to_sym])
  return c if c.is_a?(String)

def []=(key, value)

    value = {:value => value}
  end
  value = configatron.mack.cookie_values.to_hash.symbolize_keys.merge(value)
  self.all_cookies[key] = value
  self.response.set_cookie(key, value)
end

#all ⇒ Object

Returns both cookies that came in as part of the request, as well as those set on to the response. This is useful when you set a cookie in a filter or an action and want to access it in another filter or action before the request/response has been fully completed.
