Varnish is a web accelerator platform, which caches info for faster response times. It is sometimes referred to as a caching HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a visitor loads a particular webpage, the content is requested by the web browser, and then the web server processes this request and sends back the necessary info. If Varnish is enabled for a particular website, it will cache its pages on the first request and in case the user accesses a cached page for a second time, the information will be delivered by the accelerator platform instead of the server. The increased load speed is a result of the substantially faster response time that Varnish offers as compared with any server software. At the same time, this doesn’t mean that the site visitors will continue being served the same content over and over again, since any change on any of the pages is reflected in the content that the Varnish platform keeps in its system memory.
Varnish in Hosting
We offer Varnish as an optional upgrade with each Linux hosting package and if you’d like to use it, you can add it to your account through the Upgrades menu in your Hepsia hosting Control Panel. There are two separate features that can be upgraded – the instances and the system memory. The first one depends on the number of the websites that you wish to use Varnish for and the second one, which comes in increments of 32 megabytes, pertains to the maximum amount of data that the platform can cache at any given time. Hepsia’s easy-to-use graphical interface will enable you to switch off or to restart any instance, to check in-depth logs or to erase the platform’s cache with just one click. For maximum results, you can use a dedicated IP for the websites that will use the caching platform. With Varnish, your website will load substantially faster, meaning more happy site users and prospective customers.
