What are session cookies?

What are session cookies and what’s their purpose when surfing the internet? Compared to regular persistent cookies, session cookies are temporarily stored on a device.

HTTP/3 explained

HTTP/3: the next Hypertext Transfer Protocol explained simply

The plan is for HTTP/3 to soon replace its predecessor HTTP/2 as the new HTTP standard. HTTP/3 combines the properties of HTTP/2 and QUIC, and should make data transfer between clients and servers significantly faster. We will explain why the IETF is already introducing a new version four years after the HTTP/2 standard and what HTTP/3 can do.

HTTP-Header

The HTTP header - an overview for Internet users

In addition to the actual data that users see in a browser, a browser and server exchange more information in the background than meets the eye. In this article you will learn what a browser’s request and the server's response in the HTTP request and response headers say, what the HTTP fields mean and how you can read them yourself if you are interested.

Redis tutorial

Redis tutorial: an introduction to the database technology

Working with this in-memory database is not that difficult, but without an easily understandable Redis tutorial, one can quickly become discouraged. Here you will learn how to install the database, configure it, and enter data. We will also show you how to add, get, and delete data step by step.

TXT records

TXT resource records

TXT records are a highly flexible type of DNS resource record which can be used for a wide variety of purposes, such as verifying the domain for Google services like Google Analytics or providing the public key for the DKIM signature, to name just a few examples. We’ll explain what TXT records are, how to create them and how to look them up.

QUIC – the Internet Transport Protocol based on UDP

QUIC: What is behind the experimental Google Protocol?

Quick UDP Internet Connections (QUIC for short), is an experimental network protocol from Google. Further development of the protocol is being driven by IETF, which has set up a dedicated group working towards it. The QUIC protocol is intended to offer a speed-optimized alternative to the current transport standard TCP and builds on the connectionless protocol UDP to achieve this.

What is HTTPS?

HTTPS: what it means and why it’s important

Current web browsers are increasingly refusing to accept unencrypted websites and insist that the encrypted version of the Hypertext Transfer Protocol (i.e. HTTPS) be used. Why is this important? What is actually encrypted? What information can my browser provide me with about this? Here you will find the answers to these questions.

HTTP request

HTTP requests: methods, syntax, and explanation

We encounter HTTP requests daily, even if we do not notice them. Every time we click on a link in an Internet browser, the browser sends an HTTP request to the address of the webserver. Did you know that HTTP requests can even be used to delete files on a server? In this article, you will learn about the different HTTP methods.

What is HTTP?

What is HTTP?

Every web address begins with the letters HTTP. But what does HTTP mean? And why is it important? We’ll show you what you need to know about the Hypertext Transfer Protocol, one of the oldest and most important internet protocols that is required for your web browser to communicate with the web server. So, how exactly does it work?

Object-oriented databases

Object-oriented databases: the insider tip in database models

Most IT projects depend on relational databases, but alternatives exist. Object-oriented databases may only occupy a small niche, but the corresponding systems provide several advantages. Instead of distributing everything across different tables, all related attributes are brought together in one object. How does that work?
