Varnish is a web application accelerator platform, which caches content for faster access. It is occasionally called an HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor opens a specific web page, the content is requested by the browser, and then the web server processes this request and delivers the needed information. If Varnish is enabled for a certain website, it will cache its pages on the first request and if the visitor opens a cached page again, the content will be delivered by the accelerator platform and not by the server. The accelerated load speed is a result of the substantially faster response time that the Varnish platform offers as compared to any web server software. Of course, this does not mean that the users will keep seeing the exact same content again and again, because any modification on any of the web pages is reflected in the content that Varnish stores in its memory.

Varnish in Website Hosting

We offer Varnish as an optional upgrade with each Linux website hosting and if you’d like to use it, you can add it to your shared web hosting account through the Upgrades menu in your Hepsia hosting Control Panel. There are two different features that can be upgraded – the number of instances and the system memory. The first one depends on the number of the Internet sites that you want to employ Varnish for and the second one, which is available in increments of 32 MB, indicates the total amount of data that the platform can cache at any particular time. The Hepsia Control Panel’s time and effort saving GUI will enable you to shut down or to reboot any instance, to check detailed logs or to delete the platform’s cache with just a click. For optimal results, you can use a dedicated IP address for the websites that will use the caching platform. With Varnish, your site will load much faster, which means more happy website users and potential clients.

Varnish in Semi-dedicated Hosting

The Varnish content caching platform is part of the basic set of services that you’ll obtain in case you choose to host your websites in a semi-dedicated server account. You can enable it for any of your Internet sites through our advanced Hepsia hosting Control Panel. The default amount of system memory that the Varnish caching platform can use to cache data is 64 megabytes, but if you decide that you want more, you can upgrade this amount of memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform simultaneously. Since these two things are not bound to each other, you can use a couple of Internet sites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for a single web site. Varnish works best when you set a dedicated IP for the Internet sites that utilize its power. Hepsia will provide you with an easy means of rebooting any instance. Furthermore, you will be able to delete the cached contents with only a click.

Varnish in Dedicated Web Hosting

If you order a dedicated server with the Hepsia Control Panel, you will get the Varnish platform at no additional cost and you’ll exert full control over it via a rather intuitive GUI – you will be able to start, to cancel or to reboot an instance, to view a comprehensive log, to clear the cache for any website and much more. The Varnish caching platform will have several gigabytes of memory at its disposal, so even if you have traffic-intensive Internet sites with a huge number of visitors, you’ll notice the considerably faster site load speeds and the less load on the dedicated machine. This will become a fact soon after you begin using the Varnish platform, since it will need some time to cache the site content that people open. You can make the most of the platform’s capabilities if the sites that are using it use also a dedicated IP, but owing to the fact that your server comes with a few IPs by default, you won’t have to pay anything on top of the monthly charge for the server itself.
