HTTPprotokolla

HTTPprotokolla, or Hypertext Transfer Protocol, is the foundation of data communication for the World Wide Web. It is an application-layer protocol used for transmitting hypermedia documents, such as HTML. HTTP defines how messages are formatted and transmitted, and what actions web servers and browsers should take in response to various commands.

The protocol works on a client-server model. A web browser (the client) sends an HTTP request to a web server. The server processes the request and sends back an HTTP response, which typically contains the requested resource or an error message. These requests and responses are made up of headers, which provide metadata about the request or response, and a body, which contains the actual data being transmitted.

HTTP is a stateless protocol, meaning that each request is independent of any other request. This simplicity allows for efficient communication. However, for applications requiring persistent connections or more complex interactions, protocols like HTTP/2 and HTTP/3 have been developed, offering improvements in performance and efficiency. Despite these advancements, the core principles of HTTP remain central to how we access and interact with information online.
