Varnish is a web app accelerator, which has been gaining a lot of popularity in recent years, as it can increase the load speed of any website, at times even by 100%, based on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall server load and to improve the access speed for the site visitors. Each time a visitor accesses a page on a given Internet site, the web browser request is processed by the web server and the requested content is sent as a reply. If Varnish is enabled, it caches the pages that the website visitor opens and if any of them is loaded once more, it’s fetched by Varnish and not by the web server directly. The increase in the performance is due to the fact that the accelerator processes the browser requests considerably quicker than any web server, which results in much faster browsing speeds for the site visitors. If any data is updated meanwhile, the cached web pages will also be ‘refreshed’ the next time someone accesses them.
Varnish in Hosting
Varnish comes as an optional upgrade with each of our hosting
. You can add it to your account from the Hepsia Control Panel, which is offered with all shared web hosting plans and you will get a very easy-to-work-with interface, which will give you complete control over the content caching platform. Using one-click quick-access buttons, you can restart or remove any of the instances, in other words – Varnish will no longer work for a given Internet site. You can also view a comprehensive log file or delete the cache associated with any of the websites. When you add Varnish to your hosting plan, you will be able to choose the maximum amount of system memory that will be at your disposal for data 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 best performance, you can set a dedicated IP for the websites that will use Varnish. This will enable you to take full advantage of your Internet sites and to have lots of pleased website visitors.
