HTTP Evolution
HTTP Evolution Evolution and Difference HTTP / 1.1 vs HTTP / 2 vs HTTP / 3
Slow web. Long load? Maybe the problem isn't with code, but with Protocol!
HTTP / 1.1 - Classic Era (The Old Way)
Run on sequential TCP. The main problem is that the queue is called Head-of-Line Blocking at the Application level. If the first request is slow to load, the latter has to wait a long time.
HTTP / 2 - Smarter, Faster (Smarter, Faster)
Upgrade to Binary Protocol and Multiplexing, send multiple streams back and forth in one TCP Connection with Header compression, making it much lighter.
⚠️ Caution: Even if you solve the problem at the application level, the base is still TCP. If Packet Loss occurs, it will still be Blocked at the Transport Layer level.
HTTP / 3 - The Future is Here
Rip up the original rules, change the foundation to QUIC Protocol running on UDP, break the Blocking restrictions perfectly! Each Stream is separate, and comes with 0-RTT features, reconnect, and enforce Built-in TLS 1.3 encryption for maximum security.
(Which Should You Use?):
Legacy older systems may still rely on HTTP / 1.1, but modern Apps should currently stand at least at HTTP / 2, and if you want Best Performance, HTTP / 3 is recommended.
