Varnish is a web accelerator platform, which caches data for quicker access. It’s occasionally called an HTTP reverse proxy too and it works between a web server and a web browser. When a site visitor opens a certain page, its content is requested by the browser, and then the web server processes this request and sends back the requested content. If Varnish is activated for a website, it will cache its pages at the first visit and if the user visits a cached page once more, the content will be delivered by the caching platform instead of the server. The accelerated speed is an end result of the substantially faster response time that the Varnish platform offers as compared to any server software. At the same time, this doesn’t mean that the visitors will continue seeing the exact same content over and over again, as any update on any of the pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with all our shared plans. You can add it to your web hosting account through the Hepsia hosting Control Panel, which comes with all shared web hosting packages and you’ll get a rather user-friendly GUI, which will grant you complete control over the caching system. Using 1-click fast-access buttons, you can reboot or turn off any of the instances, in other words – Varnish will no longer be enabled for a given Internet site. You can also check a comprehensive log or clear the cache for any of the websites. When you add Varnish to your shared hosting plan, you’ll be able to choose the maximum amount of system memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for best performance, you can assign a dedicated IP address to the sites that will use Varnish. This will allow you to get the most out of your websites and to have plenty of pleased website users.
