Varnish is a data caching platform, which is occasionally called an HTTP reverse proxy. It is a web app accelerator tool that can increase the loading speed of a site by up to one thousand percent, depending on its content. Anytime a visitor opens any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor loads it again. In this way, the web browser request from the visitor is not handled by the web server and the page will load substantially faster, since Varnish can deliver data many times faster than any server software. The result will be a substantially faster loading site, which means an enormously improved browsing experience. In case any of the cached pages is updated on the actual site, the data that Varnish saves in its memory is updated as well, so the site visitors will never see old content.

Varnish in Hosting

You can make use of Varnish’s potential and increase the speed of your sites irrespective of the hosting package that you have chosen and you can enable and set up the data caching platform with several clicks of the mouse using the intuitive GUI offered by our cutting-edge Hepsia hosting Control Panel. During the procedure, you’ll be able to select two different things – how many websites will use Varnish, i.e. the number of instances, and how much content will be cached, i.e. the amount of system memory. The latter is available in increments of 32 MB and is not linked to the number of instances, so you can add more instances with less memory and vice versa. In case you have plenty of content on a particular Internet site and you draw numerous site visitors, more system memory will give you a better result. You may also consider using a dedicated IP for the websites that will use Varnish. Hepsia will offer you simple 1-click buttons for switching off or rebooting any instance, for clearing the cache for any website and for viewing exhaustive logs.
