Varnish is a website accelerator tool, which has been gaining a lot of popularity lately, because it can increase the loading speed of any website, sometimes even by 100%, based on the content. This tool is occasionally called a caching HTTP reverse proxy as well and is used to reduce the overall load on the physical machine and to increase the browsing speed for the website visitors. Whenever a visitor opens a page on a given website, the browser request is handled by the web server and the requested information is delivered as a reply. If Varnish is activated, it caches the pages that the visitor opens and in case any of them is loaded 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 handles the browser requests substantially quicker than any web server, which results in much faster browsing speeds for the website visitors. In case any data is modified meanwhile, the cached webpages will also be ‘refreshed’ the next time someone opens them.
Varnish in Shared Hosting
Varnish is available as an optional upgrade with all our shared hosting. You can add it to your website hosting account through the Hepsia Control Panel, which comes with all shared packages and you will get an exceptionally easy-to-use GUI, which will give you full control over the caching platform. Using one-click fast-access controls, you can restart or discontinue any of the instances, in other words – Varnish will no longer be activated for a certain Internet site. You can also see an in-depth log or clear the cache for any of the Internet sites. When you add Varnish to your hosting package, you’ll be able to choose the total amount of system memory that will be available to you for content caching purposes and how many websites will use Varnish. You can always order more memory in increments of 32 MB and, for optimum performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will permit you to take full advantage of your websites and to have plenty of satisfied website users.
