Varnish is a web application accelerator platform, which caches content for the sake of quicker access. It is sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a visitor loads a given webpage, the content is requested by the Internet browser, and then the server handles this browser request and sends back the requested information. If Varnish is activated for a given website, it will cache the pages at the very first request and if the visitor opens a cached page once more, the info will be delivered by the accelerator platform instead of the web server. The improved load speed is a result of the significantly faster response speed that the Varnish platform offers as compared with any web server software. Of course, this does not mean that the users will keep seeing the exact same content over and over again, since any modification on any of the web pages is reflected in the content that Varnish stores in its memory.

Varnish in Shared Website Hosting

You can unlock Varnish’s full potential and enhance the speed of your websites regardless of the shared website hosting package that you’ve selected and you can add and configure the data caching platform with several clicks through the simple-to-work-with graphical interface offered by our cutting-edge Hepsia hosting Control Panel. During the process, you will be able to select two different things – how many Internet sites will employ the Varnish caching platform, in other words – the number of instances, and how much data will be cached, i.e. the amount of memory. The latter is offered in increments of 32 megabytes and is not tied to the number of instances, so you can use more instances with less memory and vice versa. If you’ve got plenty of content on a certain Internet site and you win many site visitors, more system memory will give you a better result. You may also consider using a dedicated IP address for the websites that will use the Varnish platform. Hepsia will provide you with simple one-click controls for switching off or rebooting any instance, for erasing the cache associated with each site and for checking elaborate logs.

Varnish in Semi-dedicated Hosting

The semi-dedicated hosting packages offered by our company will permit you to use Varnish as soon as your brand new semi-dedicated server account has been created, since the content caching platform is available by default. 64 megabytes of system memory will be assigned to Varnish the moment your account is enabled, so you can make use of this workload distribution software as soon as your site has been launched. If you need more system memory, you can order 32 MB at a time from the Upgrades section of the Hepsia Control Panel and it will be allocated to your semi-dedicated machine in an instant. You can also increase the number of the sites that use Varnish, or the so-called ‘instances’, which are not directly bound to the amount of memory that you use, which means that you will have more freedom. The caching platform will enormously decrease the load on the semi-dedicated machine generated by your sites, so your visitors can enjoy fast-opening pages. You’ll be able to manage Varnish without efforts from the Hepsia Control Panel using quick-access controls. You will be able to start/deactivate any of the instances that you’ve got, to delete the cache associated with any of your Internet sites or to view system log files.
