Varnish is a web accelerator platform, which caches data for the sake of quicker access. It’s occasionally referred to as an HTTP reverse proxy too and it interacts between a web server and its users. When a site visitor accesses a particular page, its content is requested by the Internet browser, and then the web server handles this browser request and delivers the required content. If Varnish is enabled for a particular site, it will cache its pages at the very first request and in case the visitor accesses a cached page once again, the content will be delivered by the accelerator platform instead of the server. The improved loading speed is a result of the significantly faster response speed that Varnish offers as compared to any server software. Of course, this does not mean that the site visitors will continue seeing the same content over and over again, because any change on any of the pages is reflected in the content that Varnish keeps in its memory.

Varnish in Shared Website Hosting

In case you host your Internet sites under a shared website hosting account with our company, you will be able to add Varnish with a couple of mouse clicks from your Control Panel. The platform is available as an upgrade with all our shared packages and you can choose how many websites will use it and the maximum storage space that will be used for the cached content. The two upgradeable features 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 need a lot of memory for one large-scale website or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform in case the websites use a dedicated IP. With the hosting Control Panel, you can easily start/reboot/stop an instance, delete the cached contents individually for each site which employs Varnish or view an exhaustive system log file.
