Oh... I've been waiting for this lecture so long that I bought it as soon as it came out! I'm also watching the new spring lectures. Whenever I see Younghan, I always see his passion for programming, so I respect him a lot and want to emulate him. I always get excited when I listen to a good lecture, and I feel so good about learning something new. I think it's common sense that HTTP or networks are really important knowledge for web developers. Thank you for providing such a good lecture, and I look forward to other spring lectures that will come out in the future.
