How a resource is transferred in HTTP

About

HTTP got it in its name HyperText transfer protocol is a transfer protocol also known as fetch.

This article explains how a transfer of a resource happens via HTTP.

Steps

A user-agent (browser, application) sends a request to a http server
the http server responds back with a response that encapsulates/contains a resource, where:
- the body contains the content of the resources
- the content type contains the type of resource (ie HTML, image, …)
- and more.
the user-agent (browser, application) parses the response and recreate the resource
the user-agent (browser, application) can then:
- cache it
- and/or saved it as file

By entering an URL in your browser, you are doing a get request and most of the time, the resource returned is an HTML page but you can get all type of resource (image, pdf, …)
