Your statement that blade servers are similar in size to rackmount servers (blade servers are typically similar to 10U in size), your description of dynamic content as 'moving content' (dynamic content refers to content that varies based on user requests and requires computation), your assertion that forward proxies are located behind web servers (forward proxies are located immediately behind the client for security purposes, such as hiding client information or filtering. Of course, they also perform caching. To fulfill this role, they must be located directly behind the client), and so on—there is too much incorrect information.
Thank you for your valuable feedback. Regarding the first point you raised about blade server size, while 10U servers are indeed the most common, 6U sizes also exist. In the past, even 4U rack servers were considered large, so from that perspective, stating that blade server sizes are similar to rack-mount servers, as you mentioned, might seem like a misrepresentation. However, considering that recent rack-mount servers also come in 8U and 10U GPU server sizes, I believe it's not entirely incorrect to say that blade server sizes are similar to rack servers. Although I used that expression along with an image, it's still possible for students like yourself to think otherwise. Therefore, I will update the materials to reflect this information. Regarding the second point you raised about the explanation of dynamic content, when I was producing the lecture video, I tried to explain it to students using the simplest analogy possible, which led me to express dynamic content literally as "moving content." I apologize for causing confusion to viewers due to the lack of an additional explanation that it is content that changes according to user requests. I will also update the video by adding this content to the materials. Finally, explaining a forward proxy server as being located behind a web server in the form of a cache server is a clear error. When I produced the video, I placed it behind the web server to explain the caching function and differentiate it from a reverse proxy server, but this information is indeed incorrect. I will revise and re-produce the materials and video content, upload them, and then add a comment to the relevant lecture. Once again, I sincerely apologize for any inconvenience caused by providing incorrect information. In the future, I will put more effort into content creation and verify everything meticulously. I wish you continued success.
The related content has been added to the class notes for Lecture 1's 'Servers, Roles, and Types' and 'Server Hardware and Software' parts, and the video has been revised and uploaded. We sincerely apologize again for causing inconvenience with the incorrect information.
