It was really the best lectureㅠㅠ I was frustrated because I couldn't understand and understand clearly even though I studied books related to HTTP diligently, but after taking this lecture, I was able to understand and learn a lot about HTTP and the web, which is really great. I'm so happy that I can finally explain well what process and what is created when a web browser (client) makes a request to a server. And I also learned about Stateless, HTTP requests, response messages, headers, cookies, and cache, so I think the frustration and confusion I've felt in my work will be resolved, which is really great. I'll listen hard to the next lecture too. Thank you so much!
