This lecture was also very well-received. If MVC Part 1 was a lecture that taught me in detail about the MVC structure and basic contents, this MVC Part 2 was a lecture that taught me in detail about messages, verification, cookies, sessions, interceptors, exceptions, etc., which I had heard a lot about as necessary contents for development but did not know how to use. It was good to learn them in detail through this lecture. Whenever the contents learned in the Core Principles lecture, HTTP lecture, and MVC Part 1 lecture came up in this lecture, I reviewed the contents I had learned before, and when I couldn't remember them well, I reviewed the contents I had learned before, and it felt like the contents I had learned so far were more connected. I will study hard for the next DB lecture as well. Thank you for making a good lecture. I would also like to thank Kim Young-han and the supporters who always answer my questions.
