Varnish is a web app accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the load speed of any Internet site, at times even by one hundred percent, depending on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to reduce the overall server load and to improve the access speed for the website visitors. Whenever a visitor accesses a page on a specific website, the web browser request is taken care of by the web server and the requested content is served as a reply. If Varnish is enabled, it caches the pages that the visitor opens and in case any of them is accessed once again, it’s served by Varnish and not by the server directly. The increase in the performance comes from the fact that the accelerator processes the browser requests significantly faster than any web server, which leads to much faster browsing speeds for the visitors. If any content is changed meanwhile, the cached webpages will also be updated the next time somebody tries to open them.

Varnish in Website Hosting

You can unlock Varnish’s full potential and improve your websites’ load speed regardless of the website hosting plan that you have picked and you can add and configure the content caching platform with a few mouse clicks through the user-friendly graphical interface offered by our next-gen Hepsia Control Panel. During the procedure, you will be able to choose two separate things – how many sites will employ the Varnish caching platform, i.e. 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 MB and is not tied to the number of instances, so you can use more instances and less memory and vice versa. In case you’ve got plenty of content on a given website and you attract numerous website visitors, more system memory will give you better results. You may also consider using a dedicated IP address for the sites that will use the Varnish platform. Hepsia will provide you with simple 1-click controls for deactivating or rebooting any instance, for erasing the cache associated with any site and for checking elaborate logs.

Varnish in Semi-dedicated Hosting

All our Linux semi-dedicated hosting come with Varnish by default, so you can use the web accelerator tool and improve the speed of any site that you host on our semi-dedicated servers. You’ll get 64 MB of memory dedicated to Varnish at no additional charge and you’ll be able to activate an instance with no more than a few clicks from the Hepsia Control Panel, which comes with the semi-dedicated server packages. If you need more memory, the latter is available in increments of 32 MB in the Upgrades section of the Control Panel and it will be at your disposal immediately. You can also order more instances as an upgrade, so you can decide whether a lot of data will be cached for a single website or whether the available memory will be used by several sites. Hepsia will enable you to restart or to deactivate any instance, to check the system log associated with it or to clear the cached data using single-click controls. To get the most out of Varnish, you can get a dedicated IP address for the Internet sites that will use it.
