In this article, we'll discuss the best free and low-cost SSL certificate authorities that offer affordable SSL certificates. We'll look at the pros and cons of each CA, the types of SSL certificates they offer, and how to install ... Read More

Varnish is an HTTP accelerator that improves the performance of web applications by caching frequently requested content in memory. It is a powerful tool that can speed up your website and reduce server load by serving cached content directly to users instead of processing requests every time they visit. In this article, we'll take a look at how to install Varnish and perform load testing using Apache Benchmark. Prerequisites Before we begin, make sure you have the following software installed on your server − Apache web server Varnish Apache Benchmark (ab) If you don't have these installed, you ...

What is Django? Django is a well-known web framework written in Python that enables developers to create web applications more quickly. The views in a Django application are the ones in charge of processing HTTP requests and sending back HTTP answers. Class-based views, also known as CBVs, are an alternative to function-based views, also known as FBVs. They provide a method to designing views that is more object-oriented. Python classes that inherit from one of Django's built-in view classes are what are referred to as CBVs in the Django framework. These classes provide methods that correlate to the various HTTP ...

HTTP stands for Hypertext Transfer Protocol. Protocol is a set of rules that tells what is the correct procedure to be followed in normal situations while sharing data in networking. HTTP is a type of standard language or one kind of application protocol for transferring hypermedia documents such as HTML pages. It allows different users to communicate through data on the world wide web(WWW). HTTP is not secure as it doesn’t encrypt the data that is transmitted between clients(users) to servers. For example, if you are visiting any site and somewhere it asks for your email address and other ... Read More

The IP address and the URL are the two ways to identify resources on the internet (Uniform Resource Locator). An online resource, similar to a web page or an image, can be accessed by clients or users using a URL, which is a human readable string. For example, you can browse a website using the URL "https//www.tutorialspoint.com". The hostname (in this case, ("www.tutorialspoint.com"), the protocol being used (then, " https"), and sometimes a particular file path or set of query parameters which includes in the header information. Any Internet-connected device would have an IP address, which is a numerical ... Read More

In this tutorial, we will learn about Max parallel HTTP connections in a browser. To know more about this topic, we will first understand what parallel connections are, the reasons behind blocking and how to solve it, and the browser limitations. Parallel Connections By entirely requesting the original HTML page, the first embedded item, the second embedded object, etc., a browser may naively process each embedded object in sequence. But it moves too slowly! HTTP enables clients to establish connections and parallelly carry out numerous HTTP transactions. Parallel Connections Could Speed Up Page Loading. If composite pages with embedded objects ... Read More

In this tutorial, we will learn how access control allows the origin header to work. Access-Control-Allow- Origin is a header for CORS. With CORS or cross-origin resource sharing, browsers can permit a website hosted at origin A to request resources from origin B. Origin is a mix of port, hostname, and scheme, such as http://tutorialspoint.example.com:5000/, rather than just the hostname. Here is an illustration of how this is put into practice − I want to obtain resources from origin B, which is http://yoursite.com, and origin A:https://www.tutorialspoint.com. ... Read More

What is HTTP Flooding?HTTP flood is a sort of Distributed Denial of Service (DDoS) attack in which an attacker attacks a web server or application using seemingly valid HTTP GET or POST requests.HTTP flood assaults are volumetric attacks that frequently employ a botnet "zombie army"—a collection of Internet-connected computers that have been maliciously taken over, usually with the help of malware such as Trojan Horses.HTTP floods are a sophisticated Layer 7 assault that does not involve corrupted packets, spoofing, or reflection techniques and requires less bandwidth to bring down the targeted site or server than other attacks. As a result, ... Read More
