Varnish is a data caching platform, which is sometimes referred to as an HTTP reverse proxy. It’s a web application accelerator tool that can accelerate the load speed of a site by up to one thousand percent, based on the content itself. Each time a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server if 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 open considerably faster, as the Varnish platform can deliver information many times faster than any server software. The result will be a substantially faster loading page, which leads to a greatly improved website browsing experience. If any of the cached web pages is updated on the actual Internet site, the content that Varnish saves in its memory is ‘refreshed’ too, so the site visitors won’t end up seeing outdated information.

Varnish in Web Hosting

Varnish comes as an optional upgrade with each and every Linux web hosting and if you wish to use it, you can add it to your web hosting account via the Upgrades menu in your Hepsia Control Panel. There’re two separate things that can be upgraded – the number of instances and the memory. The first one depends on the number of the websites that you would like to use Varnish for and the second one, which is offered in increments of 32 MB, pertains to the maximum amount of content that the platform can store at any particular moment. Hepsia’s simple-to-use graphical interface will permit you to remove or to restart any instance, to check detailed system logs or to clear the platform’s cache with just a click. For optimal results, you can use a dedicated IP address for the sites that will use the caching platform. With Varnish, your site will open tremendously faster, meaning more satisfied site users and prospective customers.
