Varnish is a website accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any Internet site, at times even by 100%, depending on the content. This tool is sometimes called a caching HTTP reverse proxy too and is used to reduce the overall server load and to boost the browsing speed for the site visitors. Every time a visitor accesses a page on a given Internet site, the browser request is handled by the web server and the requested data is delivered as a response. If the Varnish accelerator is enabled, it caches the pages that the visitor opens and if any of them is accessed for a second time, it’s fetched by Varnish and not by the web server directly. The improvement in the overall performance is due to the fact that the accelerator processes the browser requests tremendously faster than any web server, which leads to much faster browsing speeds for the site visitors. In case any data is updated meanwhile, the cached webpages will also be ‘refreshed’ the next time somebody tries to open them.
Varnish in Hosting
Varnish is offered as an optional upgrade with each of our hosting. You can add it to your account via the Hepsia Control Panel, which is offered with all shared web hosting packages and you’ll get a pretty intuitive graphical interface, which will grant you complete control over the content caching platform. Using 1-click quick-access controls, you can reboot or discontinue any of the instances, in other words – Varnish will no longer be activated for a specific website. You can also see an in-depth log file or clear the cache for any of the Internet sites. When you add Varnish to your shared web hosting package, you’ll be able to select the maximum amount of system memory that will be at your disposal for caching purposes and how many sites will use Varnish. You can always order more memory in increments of 32 megabytes and, for top performance, you can assign a dedicated IP to the websites that will use Varnish. This will enable you to take full advantage of your websites and to have numerous satisfied site users.
