HTTP is an application-layer protocol for transmitting hypermedia documents, such as HTML. It was designed for communication between web browsers and web servers, but it can also be used for other purposes, such as machine-to-machine communication, programmatic access to APIs, and more.
HTTP is designed to permit intermediate network elements to improve or enable communications between clients and servers. High-traffic websites often benefit from web cache servers that deliver content on behalf of upstream servers to improve response time.
HTTP is the protocol behind nearly all communication on the web. A browser loading a page sends an HTTP request for the HTML document, parses the response, then sends additional requests for stylesheets, scripts, images, fonts, and other subresources.
