Varnish is a website accelerator platform, which caches data for quicker access. It’s occasionally referred to as an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a visitor loads a specific page, its content is requested by the web browser, and then the web server handles this browser request and sends back the needed content. If Varnish is enabled for a particular website, it will cache the pages on the very first request and if the visitor accesses a cached page once more, the information will be delivered by the accelerator platform instead of the web server. The boosted load speed is an end result of the considerably faster response speed that Varnish offers compared with any web server software. Of course, this does not mean that the users will continue being served the very same content again and again, because any update on any of the web pages is reflected in the content that the Varnish platform keeps in its system memory.

Varnish in Shared Hosting

Varnish is offered as an optional upgrade with each of our Linux shared hosting. You can add it to your hosting account from the Hepsia hosting Control Panel, which comes with all shared web hosting packages and you will get a very intuitive interface, which will grant you full control over the caching platform. Using one-click fast-access controls, you can reboot or shut down any of the instances, i.e. Varnish will no longer be enabled for a given Internet site. You can also view an exhaustive system log or clear the cache for any of the websites. When you add Varnish to your hosting plan, you’ll be able to choose 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 add more memory in increments of 32 megabytes and, for optimum performance, you can get a dedicated IP for the websites that will use Varnish. This will permit you to take full advantage of your sites and to have many pleased visitors.

Varnish in Semi-dedicated Hosting

Varnish is an essential part of the default service set that you will receive in case you choose to host your sites under a semi-dedicated server account. You can set it up for any of your websites through our advanced Hepsia hosting Control Panel. The default amount of memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you want more, you can upgrade this amount of memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, i.e. the number of the sites that can use this caching platform at the same time. Since these two things are not tied to each other, you can use several websites with the default amount of memory or you can order more memory in increments of 32 megabytes and use all of it for one single web site. The Varnish platform works best if you use a dedicated IP for the websites that utilize its power. Hepsia will provide you with an easy means of rebooting any instance. Also, you will be able to delete the cached content with just one click of the mouse.

Varnish in Dedicated Hosting

In case you order a dedicated server with the Hepsia hosting Control Panel, you will obtain the Varnish data caching platform at no additional cost and you’ll have complete control over it through a pretty easy-to-work-with graphical interface – you’ll be able to start, to delete or to restart an instance, to view a detailed log, to delete the cached data for any site and much more. Varnish will have several gigabytes of virtual memory at its disposal, so even if you run resource-heavy websites with multiple visitors, you will notice the much faster web page load speeds and the reduced load on the dedicated server. This will happen soon after you start using Varnish, as it will require some time to cache the website content that users request. You can take full advantage of the platform’s capabilities if the sites that are using it use also a dedicated IP, but considering the fact that your dedicated server comes with several IP addresses by default, you will not need to pay anything on top of the monthly charge for the machine itself.
