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!

D is definitely correct, but I'm not sure about B. I've used Apache and NGINX before, and the logs don't always show the real IP address behind a CDN.

D) You can activate the \record visitor's real IP\ function in the Alibaba Cloud CDN console, then you can directly view visitor's IP addresses from the Alibaba Cloud CDN access logs.

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

I'm not sure about option C). I don't think installing an extension module in Windows is necessary to see the visitor's real IP address.

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.

Yes, and activating the 'record visitor's real IP' function in Alibaba Cloud CDN console makes it even easier to view the IP addresses.

I agree, the X-Forwarded-For header is a common way to get the real IP address.

I agree with you, Jeanice. The visitor's real IP address can be obtained from the 'X-Forwarded-For' header and Alibaba Cloud CDN access logs.
