Varnish is a web accelerator, which has been gaining a lot of popularity in recent years, because it can increase the loading speed of any website, at times even by one hundred percent, based on the content. This tool is occasionally referred to as a caching HTTP reverse proxy as well and is used to lower the overall server load and to increase the access speed for the website visitors. Whenever a visitor opens a page on a particular website, the web browser request is handled by the web server and the requested content is served as a response. If the Varnish accelerator is activated, it caches the web pages that the site visitor opens and in case any of them is accessed again, it is fetched by Varnish and not by the web server directly. The increase in the overall performance comes from the fact that the accelerator handles the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. In case any data is edited in the meantime, the cached pages will also be updated the next time somebody accesses them.
Varnish in Web Hosting
Varnish comes as an optional upgrade with each and every Linux web hosting
and if you want to use it, you can add it to your shared web hosting account using the Upgrades menu in your Hepsia Control Panel. There are two different things that can be upgraded – the instances and the memory. The first one depends on the number of the Internet sites that you want to employ Varnish for, whereas the second, which comes in increments of 32 MB, displays the total amount of content that the content caching platform can cache at any given moment. The Hepsia Control Panel’s easy-to-use GUI will enable you to turn off or to restart any instance, to see in-depth logs or to clear the platform’s cache with just one mouse click. For optimal results, you can employ a dedicated IP for the Internet sites that will use the caching platform. With Varnish, your Internet site will load much faster, meaning more pleased site users and prospective customers.

If you’re in need of more than that, you can increase the system memory allocation. The memory itself is available in increments of 32 megabytes in the Control Panel’s Upgrades section. The same Upgrades section will allow you to enable more instances too, if you would like to use the Varnish platform with multiple Internet sites. The two things can be added independently – you can cache the content of one single traffic-intensive site or run a number of websites with the default memory allowance. You can get the most out of Varnish if you have a dedicated IP and you can order one with your semi-dedicated server package as well. Hepsia will grant you complete control over the platform and, with no more than one click of the mouse, you will be able to delete the cached data, to check a log file or to restart an instance.
