Varnish is a web accelerator, which has been gaining a lot in popularity in recent years, as it can increase the speed of any site, at times even by 100%, based on the content. This tool is sometimes called a caching HTTP reverse proxy as well and is used to reduce the overall server load and to accelerate the access speed for the website visitors. Anytime a visitor loads a page on a particular website, the web browser request is handled by the web server and the requested info is sent as a reply. If Varnish is enabled, it caches the web pages that the site visitor opens and if any of them is accessed for a second time, it’s delivered by Varnish and not by the web server directly. The boost in the performance is due to the fact that the accelerator handles the browser requests substantially faster than any web server, which results in much faster browsing speeds for the site visitors. If any content is edited meanwhile, the cached pages will also be ‘refreshed’ the next time someone accesses them.

Varnish in Website Hosting

You can take advantage of Varnish’s potential and increase the speed of your websites irrespective of the website hosting package that you’ve selected and you can add and configure the data caching platform with a couple of clicks through the easy-to-work-with GUI offered by our avant-garde Hepsia Control Panel. During the process, you will be able to select two separate things – how many Internet sites will employ the Varnish caching platform, in other words – the number of instances, and how much data will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 MB and is not bound to the number of instances, so you can add more instances with less memory and the other way around. If you’ve got plenty of content on a particular Internet site and you attract plenty of website visitors, more memory will guarantee you a better result. You may also consider employing a dedicated IP address for the websites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with easy 1-click buttons for stopping or rebooting any instance, for erasing the cache associated with any Internet site and for viewing detailed system logs.
