Varnish is a web app accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any Internet site, sometimes even by one hundred percent, based on the content. This tool is sometimes referred to as an HTTP reverse proxy as well and is used to lower the overall server load and to boost the access speed for the site visitors. Each time a visitor opens a page on a specific site, the web browser request is taken care of by the web server and the requested content is returned as a response. If the Varnish accelerator is activated, it caches the pages that the website visitor browses and in case any of them is opened once more, it’s delivered by Varnish and not by the server directly. The boost in the performance is due to the fact that the accelerator processes the browser requests substantially faster than any web server, which results in much faster browsing speeds for the visitors. If any data is modified in the meantime, the cached web pages will also be updated the next time somebody attempts to open them.
Varnish in Website Hosting
Varnish is offered as an optional upgrade with each of our Linux website hosting. You can add it to your website hosting account from the Hepsia Control Panel, which is offered with all shared packages and you’ll get a quite user-friendly interface, which will grant you full control over the content caching platform. Using 1-click quick-access buttons, you can restart or cancel any of the instances, i.e. Varnish will no longer be activated for a specific Internet site. You can also check a comprehensive log file or delete the cache associated with any of the Internet sites. When you add Varnish to your hosting plan, you’ll be able to select the maximum amount of memory that will be available to you for caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 MB and, for maximum performance, you can get a dedicated IP address for the sites that will use Varnish. This will permit you to get the most out of your Internet sites and to have plenty of pleased visitors.
