Varnish is a web application accelerator platform, which caches information for the sake of quicker response times. It’s occasionally referred to as a caching HTTP reverse proxy too and it interacts between a web server and a web browser. When a website visitor accesses a certain web page, its content is requested by the browser, and then the server handles this browser request and sends back the required info. If Varnish is activated for a particular site, it will cache its pages at the first visit and if the user accesses a cached page for a second time, the content will be delivered by the caching platform and not by the web server. The improved load speed is an end result of the much faster response time that Varnish offers compared with any server software. At the same time, this doesn’t mean that the visitors will keep being served the exact same content again and again, as any modification on any of the pages is reflected in the content that the Varnish platform caches in its system memory.

Varnish in Cloud Website Hosting

You can make use of Varnish’s full potential and boost the speed of your sites irrespective of the cloud website hosting package that you have chosen and you can add and configure the data caching platform with several clicks of the mouse using the user-friendly GUI offered by our avant-garde Hepsia Control Panel. During the process, you will be able to choose two different things – how many Internet sites will employ Varnish, i.e. the number of instances, and how much content will be cached, in other words – the amount of system memory. The latter comes in increments of 32 MB and is not bound to the number of instances, so you can use more instances and less memory and vice versa. If you’ve got lots of content on a certain site and you draw plenty of visitors, more memory will give you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish caching platform. Hepsia will offer you simple one-click controls for disabling or restarting any instance, for clearing the cache associated with any site and for checking elaborate logs.
