Varnish is a web accelerator tool, 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 100%, based on the content itself. This tool is occasionally called an HTTP reverse proxy as well and is used to decrease the overall load on the physical machine and to boost the browsing speed for the site visitors. Whenever a visitor loads a page on a specific website, the browser request is taken care of by the web server and the requested content is delivered as a response. If Varnish is activated, it caches the web pages that the visitor browses and if any of them is loaded for a second time, it’s delivered by Varnish and not by the server directly. The performance boost is due to the fact that the accelerator processes the browser requests significantly faster than any web server, which results in much faster browsing speeds for the website visitors. In case any content is modified in the meantime, the cached pages will also be updated the next time someone tries to access them.
Varnish in Web Hosting
You can use Varnish’s full potential and enhance your websites’ load speed regardless of the web hosting
package that you’ve picked and you can enable and configure the content caching platform with several clicks using the intuitive interface offered by our next-generation Hepsia hosting Control Panel. In the meantime, you will be able to choose two separate things – how many Internet sites will employ the Varnish platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 MB and is not tied to the number of instances, so you can use more instances and less memory and the other way around. In case you’ve got lots of content on a particular site and you attract a lot of visitors, more memory will give you better results. You may also consider using a dedicated IP for the sites that will use Varnish. The Hepsia Control Panel will provide you with simple one-click controls for turning off or rebooting any instance, for deleting the cache associated with any website and for checking elaborate logs.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated hosting
come with Varnish by default, so you can take full advantage of the web accelerator tool and increase the speed of any site that you host on our platform. You will get 64 megabytes of memory particularly for Varnish at no additional charge and you can activate an instance with no more than a couple of clicks through the Hepsia hosting Control Panel, which comes with the semi-dedicated packages. If you need more memory, the latter is available in increments of 32 megabytes in the Control Panel’s Upgrades section and it will be available to you instantly. You can also order more instances as a separate upgrade, so you can choose whether plenty of content will be cached for one website or if the memory will be used by multiple sites. Hepsia will permit you to reboot or to delete any instance, to view the system log file for it or to delete the cached content using one-click buttons. To take full advantage of Varnish, you can set a dedicated IP address for the websites which will employ it.
