Varnish is a web accelerator, which has been gaining a lot of popularity in recent years, as it can increase the load speed of any site, at times even by one hundred percent, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the server and to improve the browsing speed for the site visitors. Each time a visitor opens a page on a given Internet site, the web browser request is handled by the web server and the requested info is returned as a response. If the Varnish accelerator is activated, it caches the pages that the visitor browses and in case any of them is opened once more, it is delivered by Varnish and not by the server directly. The performance boost comes from the fact that the accelerator processes the browser requests considerably faster than any web server, which leads to much faster browsing speeds for the visitors. In case any data is modified in the meantime, the cached pages will also be ‘refreshed’ the next time somebody opens them.

Varnish in Shared Hosting

You can take advantage of Varnish’s potential and increase your sites’ load speed regardless of the shared hosting plan that you have selected and you can enable and configure the content caching platform with a few mouse clicks from the intuitive interface offered by our leading-edge Hepsia Control Panel. During the procedure, you will be able to select two different things – how many websites will use Varnish, in other words – the number of instances, and how much data 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 add more instances with less memory and vice versa. If you’ve got plenty of content on a particular website and you get numerous website visitors, more system memory will give you a better result. You may also consider employing a dedicated IP for the websites that will use Varnish. Hepsia will provide you with simple one-click controls for disabling or restarting any instance, for deleting the cache associated with any website and for checking elaborate system logs.

Varnish in Semi-dedicated Hosting

All our semi-dedicated hosting services include Varnish by default, so you can make use of the web application accelerator and increase the speed of any website that you host on our semi-dedicated servers. You’ll get 64 megabytes of system memory particularly for Varnish at no additional fee and you’ll be able to enable an instance with no more than a few clicks of the mouse from the Hepsia hosting Control Panel, which comes with the semi-dedicated plans. In case you need more memory, the latter is available in increments of 32 MB through the Control Panel’s Upgrades section and it will be available to you instantly. You can also add more instances as an upgrade, so you can decide if a lot of data will be cached for a single site or whether the memory will be used by multiple Internet sites. Hepsia will enable you to restart or to shut down any instance, to check the system log associated with it or to delete the cached data using single-click buttons. To take full advantage of the Varnish accelerator, you can assign a dedicated IP to the sites which will use it.
