Varnish is a content caching platform, which is sometimes called an HTTP reverse proxy. It is a web app accelerator that can boost the loading speed of a website by up to 1000 percent, based on the content itself. Each time a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor accesses it again. In this way, the browser request from the visitor is not handled by the server and the web page will load significantly faster, since the Varnish platform can deliver content many times faster than any server software. The result is a substantially faster loading site, which means an improved browsing experience. When any of the cached pages is updated on the actual Internet site, the content that Varnish saves in its memory is ‘refreshed’ too, so the site visitors won’t see out-of-date content.
Varnish in Semi-dedicated Hosting
All our Linux semi-dedicated packages come with Varnish by default, so you can take full advantage of the web accelerator and optimize the loading speed of any site that you host on our semi-dedicated servers. You’ll get 64 MB of system memory particularly for Varnish at no additional cost and you’ll be able to enable an instance with no more than a few clicks via the Hepsia Control Panel, which is included with the semi-dedicated plans. If you want more memory, the latter is offered in increments of 32 MB in the Upgrades section of the Control Panel and it will be available to you instantly. You can also add more instances as a separate upgrade, so you can choose if a lot of data will be cached for a single website or if the available memory will be used by several sites. The Hepsia Control Panel will enable you to reboot or to disable any instance, to view the system log associated with it or to delete the cached data using 1-click controls. To take full advantage of Varnish, you can set a dedicated IP for the websites that will employ it.
Varnish in Dedicated Web Hosting
All Linux dedicated servers hosting packages that are ordered with the in-house developed Hepsia web hosting Control Panel feature Varnish, which is among the pre-installed software platforms that you will get with the dedicated server. The Varnish caching platform can be activated and administered with no effort through the Hepsia Control Panel’s intuitive GUI and, with no more than one mouse click, you can view an in-depth system log, create or reboot an instance, clear the cached files for any Internet site and much, much more. Soon after you activate Varnish for a specific domain or sub-domain, it will begin caching the web pages requested by the website visitors and as soon as it has cached enough web content, you will observe a substantially faster website performance and a reduced load on the server. With Varnish-dedicated memory starting at 3 gigabytes, you will be able to use the platform for workload balancing purposes even if you host an immense number of sites on the server.
