Clickjacking Attacks: What Are They and How to Prevent ThemClickjacking refers to any attack where is user is tricked into clicking any unexpected web element unintentionally. It is a malicious practice in which the attacker tricks a user to click on another webpage who actually clicks on another page.

An Overview of HTTP and How It WorksHTTP is a protocol which allows the fetching of resources, such as HTML documents. It is the foundation of any data exchange on the Web and it is a client-server protocol, which means requests are initiated by the recipient, usually the Web browser. A complete document is reconstructed from the different sub-documents fetched, for instance text, layout description, images, videos, scripts, and more.30. HTTP Compression Optimization: How to Improve Transfer Speed and Bandwidth UtilizationCompression is an important way to increase the performance of a Web site. For some documents, size reduction of up to 70% lowers the bandwidth capacity needs. Over the years, algorithms also got more efficient, and new ones are supported by clients and servers.31.

Whether you spend your time primarily on the client or on the server, you're likely familiar with the popular ones like 200, 404, and 500. While memorizing all the codes using cat memes as a mnemonic can be helpful, let's dive deeper into what some of the most common codes mean.41.

Application Programming Interface (API): What it is and How to Use itAPIs are less like USB ports or fire hoses than they are as a person at a help desk in a foreign country. An API will not give you all of a program’s information or code (like a fire hose), because what would stop you from replicating the entire code base? Instead, an API provides you with data its programmers have made available to outside users. Even so, you have to know the language and ask the right questions to do anything with this data.49.

Gradual Development of HTTP ProtocolHTTP (HyperText Transfer Protocol) is the underlying protocol of the World Wide Web. Developed by Tim Berners-Lee and his team between 1989-1991, HTTP has seen many changes, keeping most of the simplicity and further shaping its flexibility. HTTP has evolved from an early protocol to exchange files in a semi-trusted laboratory environment, to the modern maze of the Internet, now carrying images, videos in high resolution and 3D.57.
