As a non-major, I was always curious about the network structure, and whenever I opened the developer tool, I read things like request header and payload, but I didn't really know what they were, so I just accepted them in a crude way. But after taking the class, I can see it now! I understand why you put the http lecture before MVC! It was a lecture with a beginning, development, turn, and conclusion, so I listened to it smoothly. Thank you! I'll see you in the next lecture.
