Varnish is a web application accelerator platform, which caches info for the sake of faster access. It’s sometimes referred to as a caching HTTP reverse proxy too and it interacts between a web server and its users. When a website visitor accesses a particular page, its content is requested by the Internet browser, and then the web server handles this request and sends back the needed info. If Varnish is activated for a particular website, it will cache the pages on the first request and in case the visitor accesses a cached page once more, the info will be delivered by the caching platform instead of the server. The boosted loading speed is a result of the significantly faster response time that Varnish offers compared with any server software. Of course, this does not mean that the users will keep being served the same content over and over again, since any change on any of the pages is reflected in the content that Varnish caches in its memory.

Varnish in Website Hosting

If you host your Internet sites in a website hosting account with us, you will be able to add Varnish with a few mouse clicks from your Control Panel. The caching platform comes as an optional upgrade with all our web hosting plans and you can select the number of the websites that will use it and the total storage space that will be used for the cached data. The two features that can be upgraded in the Upgrades section of the Control Panel are the amount of memory and the number of instances and they are not directly linked to each other, so you can choose whether you want plenty of memory for a single large-scale website 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 address. Using the Control Panel, you can effortlessly start/reboot/shut down an instance, delete the cached data independently for each site which employs the Varnish platform or view an exhaustive log.
