rack.session.options - 何时使用哪个？

Question

是否有区别：跳过和：延期然后分开：推迟往往用于旧版本？是否有任何用于各种选项的用例，以及何时应该在那里使用？

非常感谢。

我希望看看at these comments in the Rack source code可能会帮助你。

# :skip will not a set a cookie in the response nor update the session state 

# :defer will not set a cookie in the response but still update the session 
# state if it is used with a backend
