When Varnish receives a request, it first checks whether this request can already be served from the cache. As a so-called HTTP cache proxy, it was designed for complex websites with dynamic content and can be placed in front of a web server such as Apache or NGINX. This is where the Varnish cache comes into play. By using a full-page cache, the number of simultaneous visitors can be greatly increased.

Depending on the hardware and software setup, a web server is limited in the number of visitors it can serve simultaneously. In e-commerce, this can quickly result in falling conversions, lower turnover and increasing customer dissatisfaction. The more complex the website, the higher the load on the server and the slower the loading time. The shop systems Magento and Shopware also work in this way. In the process, data is retrieved from a database such as MySQL and converted in a programming language such as PHP into an HTML format that can be read by browsers. Nowadays, web servers often generate websites dynamically. Since setting up Varnish is relatively complex and the application is also not suitable for every online shop, we will go into more detail below about how it works, the areas of application and the configuration. Rightly so, because with the right settings, the page load time of a website can be improved enormously on the server side. Varnish is a full-page cache for Unix operating systems that is commonly referred to as a "performance booster for websites" or "web accelerator".
Shop operators often use the web accelerator Varnish for this purpose, as it enables enormous speed improvements, especially for e-commerce applications. Since the loading time of an application is of enormous importance, especially in e-commerce, server-side caching is a proven means of improving it. These can greatly accelerate the loading time of applications by avoiding computationally intensive operations. Stores customer-specific information related to shopper-initiated actions such as display wish list, checkout information, etc.In the context of web applications, there are various types of caches.
