About Course

In this modules, we will delve into the core elements of the HTTP protocol, a fundamental building block of the web. HTTP (HyperText Transfer Protocol) is how clients (such as web browsers) communicate with web servers to request and receive resources like HTML documents, images, videos, and other content. HTTP is what powers every interaction you have on the web.

You will start by learning the basics of HTTP, including what happens when you type a URL into your browser. From there, we’ll cover the different HTTP methods used to request and manipulate data. You’ll discover the roles of headers in HTTP requests and responses, and how they can be used to enhance security and ensure proper communication between clients and servers.

Throughout this modules, we’ll ensure that complex concepts are explained in simple terms and include practical examples that will help you understand how HTTP works and how to use it securely in your applications.
