Varnish is a web application accelerator platform, which caches info for the sake of quicker access. It’s occasionally called a caching HTTP reverse proxy too and it works between a web server and a browser. When a site visitor accesses a specific web page, the content is requested by the browser, and then the web server processes this browser request and returns the requested info. If Varnish is enabled for a particular site, it will cache the pages on the very first request and in case the visitor visits a cached page once again, the info will be delivered by the caching platform and not by the server. The boosted load speed is a result of the substantially faster response speed that the Varnish platform offers compared to any server software. At the same time, this does not mean that the site visitors will continue being served the exact same content again and again, since any change on any of the web pages is reflected in the content that the Varnish platform saves in its system memory.

Varnish in Shared Hosting

You can make use of Varnish’s potential and optimize your sites’ loading speed irrespective of the shared hosting plan that you’ve picked and you can add and set up the data caching platform with a couple of mouse clicks via the user-friendly interface offered by our next-generation Hepsia Control Panel. During the process, you’ll be able to choose two different things – how many sites will use the Varnish platform, in other words – the number of instances, and how much information will be cached, in other words – the amount of memory. The latter is available in increments of 32 MB and is not linked to the number of instances, so you can use more instances and less memory and the other way around. In case you have plenty of content on a specific Internet site and you attract a lot of site visitors, more memory will guarantee you a better result. You may also consider using a dedicated IP address for the sites that will use Varnish. The Hepsia Control Panel will offer you easy one-click buttons for deactivating or rebooting any instance, for erasing the cache associated with any website and for viewing elaborate logs.
