Varnish is a website accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the load speed of any website, sometimes even by one hundred percent, depending on the content itself. This tool is occasionally called an HTTP reverse proxy too and is used to decrease the overall server load and to accelerate the browsing speed for the website visitors. Anytime a visitor accesses a page on a given website, the browser request is processed by the web server and the requested info is sent as a response. If Varnish is enabled, it caches the pages that the visitor browses and in case any of them is opened again, it is delivered by Varnish and not by the web server directly. The increase in the performance comes from the fact that the accelerator handles the web requests considerably faster than any web server, which leads to much faster browsing speeds for the website visitors. If any data is modified in the meantime, the cached webpages will also be ‘refreshed’ the next time someone opens them.

Varnish in Shared Website Hosting

You can unleash Varnish’s potential and increase your websites’ speed irrespective of the shared website hosting package that you’ve chosen and you can add and set up the content caching platform with several mouse clicks through the easy-to-use GUI offered by our avant-garde Hepsia hosting Control Panel. During the process, you’ll be able to choose two different things – how many websites will employ the Varnish caching platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter comes in increments of 32 megabytes and is not tied to the number of instances, so you can add more instances and less memory and vice versa. In case you have plenty of content on a certain website and you receive 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 the Varnish platform. Hepsia will provide you with simple 1-click controls for removing or rebooting any instance, for clearing the cache associated with each Internet site and for seeing elaborate system logs.
