Varnish is a web app accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any site, at times even by one hundred percent, based on the content itself. This tool is sometimes referred to as an HTTP reverse proxy too and is used to lower the overall load on the physical server and to enhance the access speed for the website visitors. Anytime a visitor accesses a page on a specific Internet site, the browser request is handled by the web server and the requested info is sent as a response. If the Varnish accelerator is activated, it caches the web pages that the website visitor browses and if any of them is loaded once again, it’s delivered by Varnish and not by the web server directly. The increase in the performance is due to the fact that the accelerator handles the web requests substantially faster than any web server, which results in much faster browsing speeds for the website visitors. In case any data is modified meanwhile, the cached web pages will also be updated the next time someone accesses them.

Varnish in Web Hosting

You can unlock Varnish’s potential and improve the load speed of your sites regardless of the web hosting package that you have selected and you can activate and configure the platform with a few clicks using the user-friendly GUI offered by our next-generation Hepsia Control Panel. During the process, you’ll be able to select two separate things – how many websites will use Varnish, in other words – the number of instances, and how much information will be cached, i.e. the amount of system memory. The latter is available in increments of 32 MB and is not bound to the number of instances, so you can add more instances and less memory and the other way around. If you’ve got plenty of content on a particular website and you receive numerous visitors, more system memory will guarantee you better results. You may also consider employing a dedicated IP for the websites that will use Varnish. The Hepsia Control Panel will provide you with simple one-click controls for stopping or restarting any instance, for erasing the cache associated with any Internet site and for viewing in-depth logs.
