Varnish is a web application accelerator, which has been gaining a lot in popularity lately, as it can increase the loading speed of any site, at times even by one hundred percent, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to decrease the overall server load and to accelerate the access speed for the site visitors. Every time a visitor opens a page on a certain website, the web browser request is processed by the web server and the requested content is served as a response. If Varnish is activated, it caches the pages that the site visitor browses and if any of them is loaded once again, it is served by Varnish and not by the server directly. The improvement in the performance is due to the fact that the accelerator processes the browser requests substantially quicker than any web server, which results in much faster browsing speeds for the site visitors. If any content is updated meanwhile, the cached webpages will also be updated the next time somebody tries to open them.

Varnish in Web Hosting

Varnish is offered as an optional upgrade with all our web hosting plans. You can add it to your web hosting account from the Hepsia Control Panel, which is offered with all shared hosting packages and you’ll get a really user-friendly interface, which will grant you full control over the content caching system. Using 1-click fast-access buttons, you can restart or shut down any of the instances, i.e. Varnish will no longer be enabled for a specific website. You can also view a comprehensive system log or delete the cache for any of the sites. When you add Varnish to your shared web hosting plan, you’ll be able to choose the total amount of system memory that will be at your disposal for data caching purposes and how many sites will use Varnish. You can always add more memory in increments of 32 megabytes and, for optimal performance, you can assign a dedicated IP to the sites that will use Varnish. This will permit you to take full advantage of your sites and to have many pleased website visitors.
