Hypertext Transfer Protocol (HTTP)

Knowledge Base / Glossary: "Hypertext Transfer Protocol (HTTP) is a protocol used to transfer data over the internet. It is the foundation of the World Wide Web and is used to transmit virtually all data on the web, including HTML documents, images, and other media."

Hypertext Transfer Protocol (HTTP) is a protocol used to transfer data over the internet. It is the foundation of the World Wide Web and is used to transmit virtually all data on the web, including HTML documents, images, and other media.

HTTP is a client-server protocol, which means that it allows a client (such as a web browser) to send a request to a server (such as a web server) and receive a response. The request and response are made up of a series of messages that are sent between the client and the server.

The client initiates a request by sending an HTTP message to the server. The message includes a request line (which specifies the method, URL, and HTTP version), headers (which provide additional information about the request), and an optional message body (which can contain data such as form data or file uploads).

The server responds to the request by sending an HTTP message back to the client. The message includes a status line (which includes the HTTP version, status code, and reason phrase), headers (which provide additional information about the response), and an optional message body (which can contain data such as the requested resource or an error message).

HTTP is an important protocol that is used to transmit virtually all data on the web. It is used by web browsers to request web pages and other resources from web servers, and it is also used by web servers to respond to these requests. HTTP is a key technology that enables the World Wide Web and is an essential part of the modern internet.
