Varnish is a data caching platform, which is occasionally called an HTTP reverse proxy. It is a web accelerator that can accelerate the load speed of a site by up to 1000%, 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 opens it again. In this way, the browser request from the visitor is not handled by the server and the web page will load tremendously faster, since the Varnish caching platform can serve content many times faster than any server software. The result is a significantly faster loading site, which means an improved website browsing experience. When any of the cached pages is updated on the live website, the information that Varnish keeps in its system memory is updated as well, so the site visitors will never see out-of-date info.
Varnish in Website Hosting
Varnish is available as an optional upgrade with all our website hosting. You can add it to your hosting account via the Hepsia hosting Control Panel, which comes with all shared plans and you’ll get a rather intuitive GUI, which will grant you complete control over the content caching system. Using one-click fast-access controls, you can restart or turn off any of the instances, in other words – Varnish will no longer work for a certain website. You can also view a detailed system log or clear the cache associated with any of the websites. When you add Varnish to your hosting package, you will be able to select the maximum amount of memory that will be at your disposal for caching purposes and how many sites will use Varnish. You can always order more memory in increments of 32 MB and, for optimum performance, you can assign a dedicated IP to the websites that will use Varnish. This will allow you to take full advantage of your sites and to have a lot of gratified website users.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers come with Varnish by default, so you can take full advantage of the web application accelerator and improve the speed of any website that you host on our platform. You’ll get 64 megabytes of memory exclusively for the Varnish accelerator at no additional fee and you will be able to enable an instance with no more than a few clicks from the Hepsia hosting Control Panel, which is included with the semi-dedicated server 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 straight away. You can also add more instances as an upgrade, so you can decide whether lots of content will be cached for one website or whether the memory will be utilized by several sites. The Hepsia Control Panel will permit you to reboot or to stop any instance, to view the system log associated with it or to clear the cached content using 1-click buttons. To get the most out of Varnish, you can allocate a dedicated IP to the websites that will employ it.
