Combining different application systems has become increasingly important over the past few years. This trend is especially due to the increasing number of web applications being developed. In order to react to this trend, many different web services were developed that make data transfer across multiple systems possible.

HTTPS, the network protocol for TLS-encrypted data transfer online can be circumvented in some cases. The danger is that encrypted websites can be accessed via unencrypted HTTP. But the HTTPS extension HSTS (HTTP Strict Transport Security) forces website access via TLS encryption, closing the security gaps that hackers like to use to intercept the HTTPS connection during transport using...
HTTP is indispensable as a mediator between the browser and web server: Both communicate with each other using the transmission protocol on the application layer by sending various types of messages. With an HTTP request, for example, the browser can request a resource or return its own data to the server. If one of these HTTP methods doesn’t work, error 405 (Method Not Allowed) occurs.

Various operating systems, such as Windows or macOS, automatically save information about address resolution from systems and applications in the network in a DNS cache.

The purpose of this practical cache is to speed up network traffic, which is particularly important on the internet. Why it’s useful to...
For two years now, Google has been actively promoting SSL encryption for websites. The search engine giant started acknowledging data transfer protection as a ranking factor in 2014, but now wants to go one step further. Users of Google’s browser, Chrome, will soon be actively warned about websites with unsafe data exchanges. This articles explains what the planned changes are and which...
Early next month, Chrome 68 will be launched and the new browser will distrust all webpages that do not have HTTPS encryption as “not secure”. This is a big step in the recent trend towards emphasizing user safety on the internet, a not entirely selfless strategy from Google. In this guide, we will explain what changes will be made, why they are happening, and how you can prepare your website...
