Varnish is a web app accelerator platform, which caches info for the sake of faster response times. It’s sometimes referred to as a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a visitor accesses a given page, the content is requested by the web browser, and then the web server handles this browser request and returns the necessary info. If Varnish is activated for a particular site, it will cache its pages on the first request and in case the user visits a cached page once more, the content will be delivered by the caching platform and not by the server. The improved loading speed is an end result of the considerably faster response speed that Varnish offers compared to any server software. At the same time, this does not mean that the users will keep being served the exact same content over and over again, as any update on any of the web pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Cloud Website Hosting

You can take advantage of Varnish’s full potential and boost your websites’ load speed irrespective of the cloud website hosting package that you have picked and you can enable and configure the content caching platform with a few clicks of the mouse via the simple-to-use GUI offered by our avant-garde Hepsia hosting Control Panel. During the procedure, you will be able to select two separate things – how many Internet sites will employ Varnish, i.e. the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter is offered in increments of 32 megabytes and is not linked to the number of instances, so you can use more instances with less memory and vice versa. If you’ve got a lot of content on a specific website and you draw numerous site visitors, more system memory will guarantee you a better result. You may also consider using a dedicated IP for the Internet sites that will use Varnish. Hepsia will provide you with simple one-click buttons for turning off or restarting any instance, for clearing the cache for any Internet site and for seeing exhaustive system logs.
