Varnish is a data caching platform, which is sometimes referred to as a caching HTTP reverse proxy. It is a web application accelerator that can increase the speed of a site by up to one thousand percent, depending on the content itself. Every time a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor accesses it again. In this way, the web browser request from the visitor is not handled by the server and the web page will load significantly faster, since the Varnish platform can deliver data many times faster than any server software. The end result is a substantially faster loading site, which means an improved visitor experience. In case any of the cached webpages is updated on the actual site, the information that Varnish saves in its system memory is ‘refreshed’ as well, so the visitors won’t see old data.

Varnish in Shared Hosting

You can make use of Varnish’s full potential and accelerate the loading speed of your websites regardless of the shared hosting package that you have chosen and you can add and configure the platform with several clicks of the mouse through the simple-to-work-with interface offered by our leading-edge Hepsia Control Panel. During the process, you’ll be able to select two different things – how many Internet sites will employ Varnish, i.e. the number of instances, and how much data will be cached, in other words – the amount of memory. The latter is available in increments of 32 megabytes and is not tied to the number of instances, so you can order more instances with less memory and the other way around. If you’ve got lots of content on a specific site and you draw numerous website visitors, more system memory will guarantee you better results. You may also consider employing a dedicated IP for the sites that will use the Varnish platform. Hepsia will offer you easy one-click buttons for turning off or rebooting any instance, for clearing the cache associated with any website and for seeing elaborate system logs.
