Since I started by creating a project using Spring, I didn't know exactly how HTTP messages are transmitted on the network, or who creates them in the form of objects. As expected from a famous lecturer, it seems that the lecturer thoroughly scratches the points I was curious about. In the HTTP lecture, there were parts that I didn't understand because it was focused on concepts, but after taking the MVC lecture, I really understood it. It seems like it would be good to take both lectures in parallel. Course review... It's just the best ^_^
