When I first heard the news of Younghan's new lecture opening, my first thought was, 'Why did the HTTP lecture come out first instead of Spring Web MVC?' It may be disappointing news for those who wanted to quickly study Spring Web MVC in the wild, but for those who prefer the scholarly approach like me and didn't know much about HTTP, I think it would be more helpful to properly organize HTTP through this opportunity to understand Spring Web MVC later, as Younghan said. As expected, I was satisfied with this lecture as I watched and listened to the vast lecture materials and explanations that you prepared so that students could easily understand. Thank you for always giving great lectures.
