Varnish is a data caching platform, which is sometimes called an HTTP reverse proxy. It’s a web app accelerator tool that can increase the speed of a website by up to 1000%, depending on the content itself. Whenever a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. Thus, the browser request from the visitor is not processed by the web server and the page will open significantly faster, since the Varnish platform can deliver content many times faster than any server software. The end result will be a significantly faster loading page, which means an enormously improved visitor experience. When any of the cached web pages is updated on the live Internet site, the info that Varnish caches in its memory is ‘refreshed’ too, so the visitors won’t end up seeing old info.

Varnish in Shared Website Hosting

You can unlock Varnish’s potential and boost the load speed of your websites irrespective of the shared website hosting package that you’ve picked and you can enable and set up the content caching platform with several clicks using the user-friendly GUI offered by our avant-garde Hepsia Control Panel. In the meantime, you will be able to select two different things – how many sites will use the Varnish platform, i.e. the number of instances, and how much info will be cached, i.e. the amount of memory. The latter is available in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances and less memory and vice versa. In case you have lots of content on a particular Internet site and you gain a lot of website visitors, more system memory will give you a better result. You may also consider using a dedicated IP address for the sites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with easy one-click buttons for stopping or rebooting any instance, for deleting the cache for any site and for viewing comprehensive system logs.
