Every time I listen to Mr. Kim Young-han's lecture, I feel that the lecture style is not stiff, but rather, he teaches in a way that makes students feel more familiar, and he also explains the content in a way that makes it as easy to understand as possible, so I am very satisfied with it. If I were to come back and leave a review for this lecture, I would say that it is a very good lecture for beginners to build up their overall knowledge of HTTP, and it is a lecture that allows intermediate and advanced people who have some knowledge of HTTP to review and reorganize their knowledge of HTTP. Also, I think the biggest advantage is that you can listen to it on your mobile phone on your way to and from work without any separate settings for the lecture! I feel like I wasted 7 years in the si domain without meaning, so I am starting to study late, but Mr. Young-han's lectures are like a shower to me. As always, I am looking forward to other lectures, and I will listen to the lectures that you have made with sincerity and sincerity so that I can move to the domain I want and make them mine. Thank you always!
