Varnish is a content caching platform, which is occasionally called an HTTP reverse proxy. It’s a website accelerator tool that can increase the speed of a site by up to 1000%, based on the content itself. Every time a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor opens it again. Thus, the web browser request from the visitor is not processed by the web server and the page will open much faster, since the Varnish caching platform can serve data many times faster than any web server software. The end result will be a much faster loading site, which leads to an enormously improved visitor experience. When any of the cached web pages is updated on the actual website, the information that Varnish keeps in its memory is ‘refreshed’ too, so the visitors will not see outdated content.

Varnish in Shared Web Hosting

You can make use of Varnish’s full potential and enhance the load speed of your websites irrespective of the shared web hosting plan that you have picked and you can activate and set up the platform with several clicks using the user-friendly interface offered by our leading-edge Hepsia Control Panel. In the meantime, you will be able to select two different things – how many websites will use the Varnish caching platform, i.e. the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances and less memory and vice versa. If you’ve got lots of content on a given site and you draw lots of site visitors, more memory will guarantee you a better result. You may also consider using a dedicated IP address for the Internet sites that will use the Varnish platform. Hepsia will offer you simple one-click controls for disabling or rebooting any instance, for deleting the cache for each site and for viewing in-depth logs.

Varnish in Semi-dedicated Servers

The Varnish data caching platform is part of the standard service set that you’ll get when you choose to host your websites in a semi-dedicated server account. You can activate it for any of your Internet sites through our next-generation Hepsia Control Panel. The default amount of system memory that the Varnish platform can use to cache content is 64 MB, but in case you decide that you want more, you can upgrade this amount from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform simultaneously. As these two features are not bound to each other, you can use several sites 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 caching platform performs best if you allocate a dedicated IP to the websites that utilize its power. Hepsia will provide you with an easy way of restarting any instance. In addition, you will be able to delete the cached content with just one single click of the mouse.

Varnish in Dedicated Servers

You can use Varnish to improve the loading speed of any website that’s hosted on a dedicated server with us when the Hepsia Control Panel is installed on the machine. Not only will you get the content caching platform ready to be used at no additional charge, but you’ll also have total control over it through the Hepsia Control Panel’s user-friendly graphical interface. It will take just one click to start or terminate an instance or to clear the cached files associated with any Internet site that is using the Varnish platform and in case you’re more advanced, you can also view the platform’s system logs. Varnish comes with at least 3 gigabytes of virtual memory for data caching purposes, so even in case you run an immense number of websites on your dedicated server and they all use the Varnish platform, the difference in their performance will be obvious. You’ll just need to wait for a while till Varnish caches whatever pages the site visitors browse on their end. The platform works best if the Internet sites use a dedicated IP, but considering the fact that our dedicated servers come with 3 free-of-charge IPs, you’ll have everything you need.
