RFC 2616 (HTTP/1.1)

RFC 2616 is a formal document that defines HTTP/1.1, a protocol used for transferring information on the internet. It describes how web browsers and servers communicate, including how to request and send data, handle errors, and manage connections. The document sets rules for things like caching (storing data for faster access), maintaining connections for efficiency, and supporting multiple types of content. Understanding RFC 2616 helps in grasping how websites load, how data is exchanged, and ensures consistent communication between various internet services.
