Varnish is a web application accelerator platform, which caches information for the sake of quicker response times. It’s occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and a web browser. When a site visitor accesses a given web page, the content is requested by the Internet browser, and then the web server processes this browser request and delivers the required information. If Varnish is activated for a certain website, it will cache the pages at the very first request and if the user opens a cached page again, the information will be delivered by the accelerator platform instead of the server. The improved load speed is an end result of the considerably faster response time that Varnish offers as compared to any web server software. At the same time, this doesn’t mean that the site visitors will keep being served the exact same content again and again, since any change on any of the web pages is reflected in the content that Varnish caches in its system memory.

Varnish in Web Hosting

Varnish is offered as an optional upgrade with all our Linux web hosting packages. You can add it to your hosting account through the Hepsia hosting Control Panel, which is offered with all shared hosting plans and you will get a rather user-friendly interface, which will grant you complete control over the caching system. Using one-click fast-access controls, you can reboot or delete any of the instances, i.e. Varnish will no longer be enabled for a particular site. You can also view an in-depth system log file or clear the cache for any of the Internet sites. When you add Varnish to your shared hosting plan, you will be able to choose the maximum amount of memory that will be at your disposal for data caching purposes and how many sites will use Varnish. You can always get more memory in increments of 32 megabytes and, for maximum performance, you can assign a dedicated IP to the sites that will use Varnish. This will allow you to get the most out of your Internet sites and to have numerous happy users.

Varnish in Dedicated Servers Hosting

In case you order a dedicated server with the Hepsia Control Panel, you will get the Varnish caching platform at no additional cost and you will have complete control over it via a very easy-to-work-with GUI – you’ll be able to start, to discontinue or to reboot an instance, to view a comprehensive system log, to clear the cached data for any website and much more. Varnish will have several GB of memory at its disposal, so even if you run resource-requiring Internet sites with plenty of visitors, you’ll notice the tremendously better page load times and the less load on the dedicated server. This will become a fact shortly after you begin using the Varnish platform, since it will need a certain amount of time to cache the web pages that visitors browse. You can take full advantage of the platform’s capacity in case the websites that are using it also use a dedicated IP, but since your dedicated server includes a couple of IP addresses by default, you won’t have to pay anything on top of your monthly charge for the machine itself.
