Varnish is a web accelerator platform, which caches content for the sake of faster response times. It is occasionally called an HTTP reverse proxy too and it works between a web server and its users. When a site visitor loads a particular web page, the content is requested by the web browser, and then the web server processes this browser request and delivers the requested information. If Varnish is enabled for a particular site, it will cache the pages at the first visit and if the visitor accesses a cached page once more, the information will be delivered by the caching platform and not by the server. The increased load speed is an end result of the much faster response speed that the Varnish platform offers as compared with any server software. At the same time, this doesn’t mean that the site visitors will continue seeing the very 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 Hosting
Varnish comes as an optional upgrade with each of our hosting plans. You can add it to your account from the Hepsia hosting Control Panel, which is available with all shared hosting packages and you will get an amazingly intuitive GUI, which will grant you full control over the data caching system. Using 1-click quick-access controls, you can restart or stop any of the instances, in other words – 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 sites. When you add Varnish to your shared hosting package, you’ll be able to select the total amount of memory that will be available to you for content caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for optimum performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will enable you to take full advantage of your sites and to have a lot of satisfied website visitors.
Varnish in Dedicated Servers
All dedicated web hosting plans that are ordered with the custom-built Hepsia web hosting Control Panel include Varnish, which is among the pre-installed platforms that you will get with the dedicated machine. The Varnish platform can be configured and administered without effort via the Hepsia Control Panel’s time and effort saving GUI and, with no more than one single click of the mouse, you can check an elaborate system log, create or restart an instance, clear the cache associated with any website and much, much more. Shortly after you enable Varnish for a given domain or subdomain, it will start caching the webpages accessed by your visitors and once it has cached enough content, you will witness a tremendously better site performance and a reduced load on the server. With Varnish-dedicated memory starting at 3 GB, you’ll be able to use the software platform for workload balancing purposes even if you host lots of websites on the server.
