How does HTTP work?

World Wide Web pages are delivered through a protocol called HTTP. HTTP defines a set of rules for exchanging files and data on the internet.

HTTP is a protocol for exchanging information on the World Wide Web, the information being web pages, images, audio or video clips etc. It can be described as a series of requests from one device, followed by responses from another device. The requests and responses are made using different protocols such as Hypertext Transfer Protocol (HTTP) and Hypertext Transfer Protocol Secure (HTTPS). HTTP is an application layer protocol that provides users with access to resources over an internet connection.

Hypertext Transfer Protocol (HTTP) is the most commonly used request protocol on the web. It enables users to interact with web resources using languages like HTML. Using TCP connections, HTTP clients can transmit hypertext messages to servers who will respond with beautifully written content formatted in accordance to any HTML specification.

HTTP is an application protocol that supports a variety of tasks, like getting content and information about resources, or requesting that resources be sent to the user. All HTTP servers support GET and HEAD requests, but not all might support PUT, POST, DELETE or OPTIONS.

  • GET requests for file resources are processed without the need to have the resource open.
  • HEAD requests a specific resource
  • POST creates a new page with content, messages or data under an existing web resource
  • PUT create a new URI if necessary
  • DELETE removes
  • TRACE this tool makes it easy to see what’s been updated on a website
  • OPTIONS displays the HTTP methods that are available for a specific URL
  • CONNECT Tapping on the connection request creates a transparent tunnel on TCP/IP.
  • PATCH Slightly changes or alters an article to improve it
