Varnish is a web application 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 occasionally called a caching HTTP reverse proxy as well and is used to decrease the overall load on the physical server and to increase the browsing speed for the website visitors. Anytime a visitor opens a page on a specific website, the web browser request is taken care of by the web server and the requested info is returned as a reply. If Varnish is activated, it caches the pages that the website visitor opens and if any of them is accessed once again, it’s delivered by Varnish and not by the web server directly. The boost in the overall performance is due to the fact that the accelerator handles the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the site visitors. In case any content is updated in the meantime, the cached webpages will also be ‘refreshed’ the next time someone tries to access them.

Varnish in Shared Hosting

You can take advantage of Varnish’s potential and boost the load speed of your sites regardless of the shared hosting package that you have picked and you can activate and configure the platform with a couple of clicks through the easy-to-work-with interface offered by our innovative Hepsia hosting Control Panel. In the meantime, you’ll be able to choose two separate things – how many Internet sites will employ the Varnish platform, in other words – the number of instances, and how much information will be cached, i.e. the amount of system memory. The latter comes in increments of 32 megabytes and is not tied to the number of instances, so you can add more instances and less memory and the other way around. In case you’ve got plenty of content on a certain site and you draw a lot of website visitors, more system memory will give you better results. You may also consider using a dedicated IP for the Internet sites that will use the Varnish platform. The Hepsia Control Panel will provide you with simple 1-click buttons for switching off or rebooting any instance, for clearing the cache associated with each site and for seeing comprehensive system logs.
