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, sometimes even by 100 percent, depending on the content itself. This tool is occasionally referred to as an HTTP reverse proxy too and is used to lower the overall load on the physical server and to accelerate the browsing speed for the site visitors. Whenever a visitor loads a page on a certain site, the web browser request is handled by the web server and the requested information is served as a reply. If the Varnish accelerator is activated, it caches the web pages that the website visitor browses and if any of them is opened once again, it’s fetched by Varnish and not by the server directly. The performance increase is due to the fact that the accelerator handles the web requests significantly quicker than any web server, which leads to much faster browsing speeds for the users. If any content is updated in the meantime, the cached pages will also be ‘refreshed’ the next time somebody attempts to open them.
Varnish in Shared Website Hosting
Varnish is offered as an optional upgrade with each of our shared website hosting. You can add it to your account from the Hepsia Control Panel, which comes with all shared plans and you will get a really easy-to-work-with interface, which will give you full control over the caching system. Using 1-click fast-access controls, you can reboot or disable any of the instances, i.e. Varnish will no longer be activated for a given website. You can also see an exhaustive log or delete the cache for any of the websites. When you add Varnish to your shared web hosting plan, you’ll be able to select the maximum amount of memory that will be at your disposal for content caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for optimal performance, you can assign a dedicated IP address to the websites that will use Varnish. This will permit you to take full advantage of your Internet sites and to have lots of pleased website visitors.
