Hypertext Transfer Protocol (HTTP) Glossary Definition

HTTP is the underlying protocol used by the World Wide Web (WWW). This protocol defines how messages are formatted and transmitted on the Internet and what actions web servers and browsers should take in response to various commands.

In web, data, cloud, and DevOps environments, this term helps teams describe application infrastructure, data flow, deployment practices, integration points, or operational tooling. It is relevant to how systems are built, hosted, versioned, monitored, and maintained.

Related concepts include Authentication, Transport Layer Security and Cookie.
