Varnish is a web app accelerator tool, which has been gaining a lot of popularity lately, because it can increase the speed of any site, sometimes even by 100%, depending on the content itself. This tool is occasionally called a caching HTTP reverse proxy as well and is used to reduce the overall load on the server and to increase the access speed for the site visitors. Anytime a visitor loads a page on a particular Internet site, the web browser request is processed by the web server and the requested data is delivered as a reply. If Varnish is enabled, it caches the pages that the website visitor opens and in case any of them is opened once again, it is fetched by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator processes the browser requests significantly quicker than any web server, which results in much faster browsing speeds for the users. In case any data is updated meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody attempts to access them.
Varnish in Web Hosting
You can unlock Varnish’s potential and enhance the load speed of your websites regardless of the web hosting
plan that you’ve picked and you can add and set up the data caching platform with a few clicks of the mouse from the simple-to-use graphical interface offered by our leading-edge Hepsia hosting Control Panel. In the meantime, you’ll be able to select two separate things – how many Internet sites will employ the Varnish caching platform, i.e. the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances and less memory and vice versa. If you’ve got a lot of content on a given site and you get many website visitors, more system memory will guarantee you a better result. You may also consider using a dedicated IP address for the Internet sites that will use Varnish. Hepsia will provide you with easy one-click buttons for stopping or rebooting any instance, for erasing the cache associated with any website and for viewing elaborate system logs.
