Learn precisely what Varnish is. Know a lot more about web accelerators and their purpose.
Varnish is a web app accelerator platform, which caches info for the sake of quicker access. It’s sometimes called a caching HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor loads a given page, its content is requested by the browser, and then the server processes this browser 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 if the visitor visits a cached page again, the data will be delivered by the caching platform and not by the web server. The boosted speed is an end result of the much faster response speed that Varnish offers as compared with any web server software. Of course, this does not mean that the site visitors will continue being served the exact same content again and again, since any modification on any of the web pages is reflected in the content that the Varnish platform saves in its memory.

and if you’d like to use it, you can add it to your shared account using the Upgrades menu in your Hepsia Control Panel. There’re two separate features that can be upgraded – the number of instances and the memory. The first one depends on the number of the websites that you want to use Varnish for and the second one, which is available in increments of 32 megabytes, indicates the maximum amount of data that the data caching platform can store at any given moment. Hepsia’s easy-to-use interface will allow you to disable or to restart any instance, to check elaborate system logs or to delete the platform’s cache with just one click. For best results, you can use a dedicated IP for the websites that will use the caching platform.
