Varnish is a web application accelerator platform, which caches data for the sake of faster response times. It is occasionally called an HTTP reverse proxy as well and it interacts between a web server and its users. When a visitor loads a specific webpage, its content is requested by the web browser, and then the web server processes this request and returns the needed info. If Varnish is enabled for a certain site, it will cache the pages on the first request and if the user visits a cached page for a second time, the data will be delivered by the accelerator platform and not by the server. The boosted speed is an end result of the significantly faster response speed that the Varnish platform offers compared with any web server software. At the same time, this does not mean that the site visitors will continue being served the exact same content again and again, since any change on any of the pages is reflected in the content that Varnish caches in its system memory.

Varnish in Cloud Web Hosting

Varnish is offered as an optional upgrade with each and every Linux cloud web hosting and if you would like to use it, you can add it to your shared account via the Upgrades menu in your Hepsia Control Panel. There are two different things that can be upgraded – the number of instances and the memory. The first one depends on the number of the Internet sites that you wish to use Varnish for, whereas the second, which is offered in increments of 32 MB, pertains to the maximum amount of content that the content caching platform can cache at any particular moment. The Hepsia Control Panel’s time and effort saving GUI will permit you to turn off or to reboot any instance, to check exhaustive logs or to get rid of the platform’s cache with just one mouse click. For optimum results, you can use a dedicated IP for the sites that will use the caching platform. With Varnish, your Internet site will open significantly faster, meaning more happy visitors and potential customers.
