Varnish is a web accelerator platform, which caches content for faster access. It is occasionally called a caching HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a site visitor opens a given page, the content is requested by the web browser, and then the server handles this browser request and delivers the required data. If Varnish is enabled for a particular site, it will cache the pages at the first visit and in case the user visits a cached page once more, the data will be delivered by the accelerator platform instead of the server. The improved load speed is an end result of the substantially faster response time that the Varnish platform offers compared to any web server software. At the same time, this does not mean that the website visitors will keep being served the exact same content again and again, as any modification on any of the pages is reflected in the content that the Varnish platform stores in its system memory.

Varnish in Web Hosting

Varnish comes as an optional upgrade with each of our Linux web hosting. You can add it to your hosting account from the Hepsia Control Panel, which is available with all shared web hosting plans and you will get a truly simple-to-use interface, which will grant you full control over the data caching system. Using 1-click quick-access controls, you can reboot or remove any of the instances, in other words – Varnish will no longer be activated for a given website. You can also see an elaborate system log file or delete the cache for any of the sites. When you add Varnish to your shared hosting package, you’ll be able to select the total amount of memory that will be available to you for content caching purposes and how many websites will use Varnish. You can always add more memory in increments of 32 megabytes and, for maximum performance, you can allocate a dedicated IP address to the websites that will use Varnish. This will permit you to take full advantage of your Internet sites and to have many happy site visitors.

Varnish in Dedicated Servers Hosting

If you order a dedicated server with the Hepsia Control Panel, you will obtain Varnish at no extra cost and you’ll exert full control over it via a truly easy-to-navigate interface – you’ll be able to start, to deactivate or to restart an instance, to view a comprehensive log, to delete the cached content for any website and much, much more. The Varnish platform will have several gigabytes of system memory at its disposal, so even if you run traffic-hungry websites with lots of visitors, you’ll notice the considerably faster web page load speeds and the less load on the dedicated server. This will happen soon after you start using Varnish, since it will require some time to cache the content that people access. You can get the most out of the platform’s capabilities if the Internet sites that are using it use also a dedicated IP address, but due to the fact that your dedicated server includes a few IP addresses by default, you will not need to pay anything on top of the monthly charge for the machine itself.
