Difference between HTTP/1.0, HTTP/1.1, HTTP/2, and HTTP/3

Here’s a concise overview of the differences between HTTP/1.0, HTTP/1.1, HTTP/2, and HTTP/3:

HTTP/1.0

Introduced: 1996
Connection: Each request opens a new TCP connection.
Features: Basic request methods (GET, POST) without headers for caching or content negotiation.

HTTP/1.1

Introduced: 1997
Connection: Supports persistent connections, allowing multiple requests over a single connection.
Features: Chunked transfer encoding, improved caching mechanisms, and additional request methods (PUT, DELETE).

HTTP/2

Introduced: 2015
Connection: Uses a binary framing layer, allowing multiplexing of multiple requests and responses over a single connection.
Features: Stream prioritization, header compression, and reduced latency compared to HTTP/1.1.

HTTP/3

Introduced: 2022
Connection: Utilizes QUIC instead of TCP, which enhances performance, especially on mobile networks.
Features: Faster connection setups, improved handling of packet loss, and reduced latency.

These advancements reflect the ongoing evolution of web protocols to meet the demands for speed, efficiency, and reliability in internet communication. If you need more details on any specific version, let me know!
