Varnish is a website accelerator tool, which has been gaining a lot of popularity in recent years, because it can increase the speed of any website, sometimes even by 100 percent, depending on the content. This tool is occasionally called a caching HTTP reverse proxy as well and is used to lower the overall load on the physical server and to accelerate the access speed for the site visitors. Whenever a visitor loads a page on a given website, the web browser request is handled by the web server and the requested data is sent as a response. If Varnish is activated, it caches the web pages that the site visitor browses and in case any of them is opened once again, it’s fetched by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator handles the browser requests significantly quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is changed meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody accesses them.
Varnish in Shared Web Hosting
Varnish is available as an optional upgrade with each of our shared web hosting. You can add it to your account from the Hepsia hosting Control Panel, which comes with all shared packages and you’ll get a rather easy-to-use graphical interface, which will grant you full control over the data caching system. Using 1-click fast-access buttons, you can restart or terminate any of the instances, in other words – Varnish will no longer be enabled for a particular Internet site. You can also view an in-depth log or clear the cache for any of the Internet sites. When you add Varnish to your web hosting plan, you will be able to select the total amount of memory that will be at your disposal for caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for best performance, you can set a dedicated IP address for the sites that will use Varnish. This will permit you to take full advantage of your sites and to have many gratified site users.
