When a user requests a protected resource but has not yet authenticated (or their authentication session has expired), the initial request does not reach the back-end servers.
当还没有经过身份验证(或者身份验证会话已经过期)的用户请求受保护的资源时，最初的请求不会到达后端服务器。
If, on the other hand, the content is not in the cache or the cache entry has expired, then the edge server makes a request to the origin server to retrieve the information.
另一方面，如果在请求的内容不在缓存中或缓存已经过期，边缘服务器就会向源服务器发送请求来获得内容。
That is, if a request is made with a session ID that has expired, a new session is started using the session ID supplied with the request.
也就是说，如果以逾时的工作阶段ID提出要求，则会使用该要求所提供的工作阶段ID启动新的工作阶段。
