Varnish is a web accelerator, which has been gaining a lot in popularity in recent years, as it can increase the speed of any Internet site, at times even by 100%, 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 server and to enhance the browsing speed for the website visitors. Anytime a visitor loads a page on a given Internet site, the browser request is processed by the web server and the requested info is served as a reply. If Varnish is activated, it caches the web pages that the visitor browses and in case any of them is opened again, it is served by Varnish and not by the web server directly. The performance boost is due to the fact that the accelerator processes the web requests substantially quicker than any web server, which leads to much faster browsing speeds for the website visitors. In case any content is updated in the meantime, the cached web pages will also be updated the next time someone accesses them.
Varnish in Website Hosting
You can make use of Varnish’s potential and accelerate your sites regardless of the website hosting plan that you’ve selected and you can add and set up the data caching platform with several clicks using the intuitive interface offered by our advanced Hepsia hosting Control Panel. During the process, you’ll be able to choose two separate things – how many sites will use the Varnish caching platform, in other words – the number of instances, and how much content will be cached, i.e. the amount of memory. The latter is available in increments of 32 MB and is not tied to the number of instances, so you can add more instances with less memory and vice versa. In case you’ve got lots of content on a given Internet site and you receive many visitors, more system memory will guarantee you a better result. You may also consider using a dedicated IP address for the websites that will use the Varnish caching platform. Hepsia will provide you with easy one-click controls for switching off or rebooting any instance, for clearing the cache associated with each website and for seeing elaborate system logs.
