Varnish is a web accelerator tool, 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, based on the content itself. This tool is occasionally referred to as an HTTP reverse proxy too and is used to decrease the overall load on the physical server and to improve the browsing speed for the site visitors. Whenever a visitor accesses a page on a certain website, the browser request is taken care of by the web server and the requested info is sent as a reply. If the Varnish accelerator is enabled, it caches the web pages that the website visitor browses and if any of them is accessed once again, it’s delivered by Varnish and not by the server directly. The improvement in the performance is due to the fact that the accelerator handles the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the users. In case any data is edited meanwhile, the cached webpages will also be ‘refreshed’ the next time someone tries to access them.
Varnish in Website Hosting
You can unlock Varnish’s full potential and improve the load speed of your websites regardless of the website hosting
plan that you’ve selected and you can enable and set up the platform with a couple of clicks through the easy-to-use interface offered by our cutting-edge Hepsia Control Panel. During the process, you will be able to choose two separate things – how many sites will use Varnish, i.e. the number of instances, and how much information will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not linked to the number of instances, so you can order more instances and less memory and the other way around. If you’ve got plenty of content on a specific website and you draw plenty of website visitors, more memory will give you a better result. You may also consider using a dedicated IP for the websites that will use Varnish. The Hepsia Control Panel will offer you easy one-click buttons for removing or rebooting any instance, for deleting the cache for any website and for viewing elaborate logs.
