The Request/Response Cycle

Before you can build a web scraper, you must take a second and think about how the internet works. At its core, the internet is a network of computers connected together, discoverable through Domain Lookup System (DNS) servers. When you want to visit a website, your browser sends the website URL to a DNS server, the URL is translated into an IP address, and your browser then sends a request to the machine at that IP address. The machine, called a web server, receives and inspects the request, and makes a decision on what to send back to your browser. Your browser then parses the information sent by the server and displays content on your screen depending on the format of the data. The web server and browser are able to communicate because of the adherence to a global set of rules called the HTTP. In this chapter, you will learn some of the key points...

Security with Go

Security with Go

Since Go has become enormously popular, Go's obvious advantages, like stability, speed and simplicity, make it a first class choice to develop security-oriented scripts and applications. Security with Go is a classical title for security developers, with its emphasis on Go. Based on John Leon's first mover experience, He starts out basic forensics and intrusion detection, and then switches tack from defense to attack, for example brute force attacks and host discovery. In all, this title enables you to use Go for all your security-related tasks.
