Varnish is a web app accelerator platform, which caches data for quicker response times. It is occasionally referred to as a caching HTTP reverse proxy as well and it works between a web server and a browser. When a site visitor opens a given webpage, the content is requested by the browser, and then the server processes this browser request and sends back the required info. If Varnish is enabled for a specific website, it will cache its pages at the first visit and if the user opens a cached page again, the content will be delivered by the accelerator platform and not by the web server. The increased speed is a result of the substantially faster response speed that the Varnish platform offers as compared to any web server software. Of course, this doesn’t mean that the site visitors will keep being served the exact same content over and over again, because any update on any of the web pages is reflected in the content that Varnish saves in its memory.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with each of our shared hosting service. You can add it to your website hosting account via the Hepsia hosting Control Panel, which is available with all shared hosting packages and you’ll get a quite easy-to-use graphical interface, which will give you complete control over the content caching system. Using 1-click quick-access controls, you can restart or delete any of the instances, in other words – Varnish will no longer be activated for a certain Internet site. You can also see an in-depth system log file or delete the cache for any of the websites. When you add Varnish to your shared web hosting plan, you’ll be able to select the maximum amount of system memory that will be available to you for data caching purposes and the number of the websites that will use Varnish. You can always add more memory in increments of 32 MB and, for optimal performance, you can allocate a dedicated IP to the sites that will use Varnish. This will permit you to take full advantage of your Internet sites and to have plenty of pleased visitors.

You can also order more instances as an upgrade, so you can decide whether lots of content will be cached for a single site or whether the memory will be utilized by different Internet sites. The Hepsia Control Panel will permit you to restart or to stop any instance, to check the system log file for it or to clear the cached files using one-click controls.

This is quite enough to enhance the overall performance of several different resource-hungry Internet sites, so the better site loading speeds and the lowered server load will be perceivable.
