Varnish is a web accelerator platform, which caches info for the sake of quicker access. It’s sometimes called an HTTP reverse proxy too and it interacts between a web server and an Internet browser. When a site visitor opens a certain webpage, the content is requested by the browser, and then the server processes this request and returns the requested information. If Varnish is enabled for a certain website, it will cache the pages at the very first request and if the user opens a cached page for a second time, the data will be delivered by the accelerator platform and not by the server. The increased loading speed is a result of the much faster response time that the Varnish platform offers as compared with any web server software. At the same time, this does not mean that the website visitors will continue seeing the same content over and over again, as any update on any of the pages is reflected in the content that Varnish caches in its system memory.

Varnish in Website Hosting

If you host your Internet sites in a website hosting account with our company, you will be able to add Varnish with a couple of clicks of the mouse via your hosting Control Panel. The platform is offered as an optional upgrade with all our shared web hosting plans and you can choose how many sites will use it and the maximum amount of system memory that will be used for the cached content. The two features that can be upgraded in the Upgrades section of the Control Panel are the number of instances and the amount of system memory and they’re not directly linked to each other, so you can decide if you need a lot of memory for one large site or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform if the websites use a dedicated IP. With the Control Panel, you can swiftly start/reboot/disable an instance, clear the cached content independently for each site which uses the Varnish platform or see an in-depth system log.
