Varnish is a web accelerator platform, which caches content for faster access. It is sometimes referred to as an HTTP reverse proxy too and it works between a web server and an Internet browser. When a website visitor opens a specific page, its content is requested by the web browser, and then the server processes this request and delivers the needed info. If Varnish is activated for a certain website, it will cache its pages on the very first request and if the visitor visits a cached page once more, the information will be delivered by the accelerator platform instead of the web server. The improved loading speed is an end result of the substantially faster response time that Varnish offers compared with any web server software. At the same time, this does not mean that the website visitors will continue seeing the very same content over and over again, as any change on any of the web pages is reflected in the content that the Varnish platform saves in its memory.

Varnish in Hosting

You can make use of Varnish’s potential and enhance your sites’ loading speed regardless of the hosting package that you have selected and you can add and configure the platform with a few mouse clicks via the easy-to-work-with interface offered by our innovative Hepsia hosting Control Panel. During the process, you’ll be able to choose two separate things – how many Internet sites will use the Varnish platform, in other words – the number of instances, and how much information will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can use more instances with less memory and the other way around. If you have plenty of content on a particular website and you gain lots of site visitors, more system memory will give you better results. You may also consider using a dedicated IP address for the sites that will use Varnish. The Hepsia Control Panel will provide you with simple 1-click buttons for terminating or rebooting any instance, for deleting the cache for each Internet site and for seeing exhaustive system logs.
