Hyper Text Transfer Protocol Crash Course - HTTP 1.0, 1.1, HTTP/2, HTTP/3

HTTP is a protocol for transferring web pages, text, media, binary files and much more. It stands for hyper text transfer protocol and It is what the Internet pretty much runs on. In this video we will learn how HTTP works, how it is secured with HTTPS, will also show how to spin up an Http web server, and we will also go through the evolution of HTTP starting from HTTP 1.0 to HTTP 1.1 to HTTP/2 and eventually HTTP/3 which is still experimental. Client / server Client makes HTTP requests to a server that supports HTTP, the server (web server, http server like apache tomcat, nodejs etc..) responds back with the content. This could be an HTML page, images, JSON and much more. Slides https://payhip.com/b/uSEkQ (Members get all slides for free.

HTTP 1.1 over tcp - Persisted connection HTTP/2 over tcp - Compression - Multiplexing - Server Push - SPDY - Mostly secure by default - Negotiates protocol during TLS (NPN/ALPN) HTTP/2 over QUIC ( HTTP/3) - Replaces TCP with QUIC (udp with congestion control) 🏭 Software Architecture Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXNP6mQchJVP3S-3oKGEuw9 💾 Database Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQXjD0HOzN7P2tgzu7scWpl2 🛰 Network Engineering Videos https://www.youtube.com/playlist?list=PLQnljOFTspQUBSgBXilKhRMJ1ACqr7pTr 🏰 Load Balancing and Proxies Videos https://www.youtube.com/playlist?list=PLQnljOFTspQVMeBmWI2AhxULWEeo7AaMC 🐘 Postgres Videos https://www.youtube.com/playlist?list=PLQnljOFTspQWGrOqslniFlRcwxyY94cjj 🚢Docker https://www.youtube.com/playlist?list=PLQnljOFTspQWsD-rakNw1C20c1JI8UR1r 🧮 Programming Pattern Videos https://www.youtube.com/playlist?list=PLQnljOFTspQV1emqxKbcP5esAf4zpqWpe 🛡 Web Security Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU3YDMRSMvzflh_qXoz9zfv 🦠 HTTP Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU6zO0drAYHFtkkyfNJw1IO 🐍 Python Videos https://www.youtube.com/playlist?list=PLQnljOFTspQU_M83ARz8mDdr4LThzkBKX 🔆 Javascript Videos https://www.youtube.com/playlist?list=PLQnljOFTspQWab0g3W6ZaDM6_Buh20EWM 👾Discord Server https://discord.gg/CsFbFce Support me on PayPal https://bit.ly/33ENps4 Become a Patreon https://www.patreon.com/join/hnasr?
