In the video, Hussein Nasser walks through why older push models fizzled, how to upgrade via Extended CONNECT, the lack of HTTP/1.1 support, proxying tricks, and even YouTube notification woes. He also sprinkles in links to his Udemy courses on back-end design patterns, networking, databases, NGINX, Python, plus membership perks and extra content for the eager backend engineer.
