The Evolution of HTTP: From HTTP/1.1 to HTTP/3

The Hypertext Transfer Protocol (HTTP) is the backbone of the web, enabling communication between browsers and servers. Over the years, it has undergone significant transformations to meet the growing demands of the internet. This post dives into the key differences between HTTP/1.1, HTTP/2, and HTTP/3, exploring how each version improves performance, security, and reliability.

HTTP/1.1: The Workhorse of the Early Web

Introduced: 1997
HTTP/1.1 brought significant improvements over its predecessor, HTTP/1.0, making it the standard for the early web era. Its features allowed for a more efficient use of network connections.

Key Features:

• Persistent Connections: Reuse of a single TCP connection for multiple requests and responses.

• Chunked Transfer Encoding: Allows servers to send data in smaller chunks rather than as a complete response.

  

  Chunk Transfer

• Pipelining (rarely used): Enables sending multiple requests before receiving responses, though practical use was limited due to implementation issues.
