Varnish is a content caching platform, which is sometimes called a caching HTTP reverse proxy. It is a web accelerator that can improve the load speed of a site by up to one thousand percent, based on its content. Anytime a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor opens it again. In this way, the browser request from the visitor is not handled by the web server and the page will load considerably faster, as Varnish can serve information many times faster than any web server software. The result is a much faster loading site, which means an immensely improved visitor experience. When any of the cached webpages is updated on the actual website, the info that Varnish keeps in its memory is updated too, so the users will never end up seeing outdated data.

Varnish in Web Hosting

In case you host your sites under a web hosting account with us, you will be able to activate Varnish with a few clicks through your hosting Control Panel. The platform is offered as an optional upgrade with all our web hosting packages and you can select how many websites 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 system memory and the number of instances and they’re not directly tied to each other, so you can choose whether you want plenty of memory for one large-sized site or less memory for several smaller ones. You can unlock the full potential of the Varnish caching platform if the websites use a dedicated IP address. Using the Control Panel, you can easily start/restart/shut down an instance, delete the cached files individually for each site that uses the Varnish platform or view a detailed log.
