When using Alibaba Cloud CDN, a visitor's request will first be routed to a CDN edge node, and in the event of a cache miss at this edge node, the node will fetch data from the origin site (back-to-source request). Even with this redirection, it is possible for the origin site to see the visitor's real IP address. Which of the following statements about obtaining the visitor's real IP address are correct? (Number of correct answers: 2)

Bvisitor's real IP address is stored in the 'X-Forwarded-For' HTTP header. It can be directly obtained via Apache or NGINX logs.

B and D seem like the right choices to me. I've used Alibaba Cloud CDN before, and the real IP logging feature is super handy. No need to mess with any sketchy IIS extensions!

Haha, C is hilarious. I can just imagine someone trying to install an 'F5XForwardedFor' extension on their IIS server. That's not how it works, folks!

I think B and D are the correct options. The X-Forwarded-For header is a standard way to get the visitor's real IP, and Alibaba Cloud CDN provides a way to log the real IP directly.
