Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, as it can increase the speed of any website, sometimes even by 100 percent, depending on the content itself. This tool is sometimes called a caching HTTP reverse proxy as well and is used to reduce the overall server load and to enhance the access speed for the site visitors. Whenever a visitor opens a page on a particular website, the browser request is handled by the web server and the requested data is delivered as a reply. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and if any of them is accessed once more, it’s served by Varnish and not by the web server directly. The performance improvement is due to the fact that the accelerator processes the web requests considerably faster than any web server, which results in much faster browsing speeds for the site visitors. If any content is updated in the meantime, the cached pages will also be updated the next time somebody opens them.

Varnish in Shared Hosting

Varnish is offered as an optional upgrade with each of our shared hosting. You can add it to your account via the Hepsia Control Panel, which is available with all shared web hosting plans and you will get a pretty easy-to-work-with GUI, which will give you complete control over the data caching system. Using 1-click quick-access buttons, you can restart or terminate any of the instances, in other words – Varnish will no longer work for a given website. You can also view a comprehensive system log file or erase the cache for any of the Internet sites. When you add Varnish to your hosting package, you’ll be able to select the maximum amount of system memory that will be at your disposal for caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 megabytes and, for optimal performance, you can allocate a dedicated IP address to the websites that will use Varnish. This will allow you to get the most out of your websites and to have numerous satisfied users.
