HTTP Basics

HTTP, or Hypertext Transfer Protocol, is the foundational protocol of the web, facilitating communication between clients and servers. Mark Nottingham explains that HTTP is often confused with transport protocols like TCP, but it operates at a higher level, enabling the transfer of data such as HTML between web browsers and servers 1. He emphasizes that HTTP is a shared vocabulary for communication, providing methods like GET, POST, and DELETE to manage web interactions 1. Eberhard Wolff introduces Mark, highlighting his role in the development of HTTP/2, a major revision aimed at improving the efficiency of web communications 2.

   

HTTP Evolution

The evolution of HTTP has been marked by significant milestones, starting from its primitive version 0.9 to the more sophisticated HTTP/1.1. Mark Nottingham notes that HTTP/1.0 introduced headers and status codes, while HTTP/1.1 formalized connection reuse with the keep-alive extension, improving efficiency 3. Despite these advancements, HTTP faced challenges in performance and interoperability, leading to efforts like HTTPNG and eventually HTTP/2 4. Mark highlights the collaborative nature of these developments, with various stakeholders working to address the protocol's limitations and enhance its capabilities 5.
