Varnish is a content caching platform, which is sometimes called an HTTP reverse proxy. It’s a web accelerator that can improve the loading speed of a website by up to 1000 percent, depending on the content itself. Whenever a visitor opens 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 handled by the server and the web page will load considerably faster, since Varnish can deliver information many times faster than any server software. The end result will be a considerably faster loading website, which means a much-improved website browsing experience. When any of the cached pages is updated on the actual site, the content that Varnish saves in its memory is ‘refreshed’ as well, so the users will never end up seeing old data.

Varnish in Shared Web Hosting

In case you host your Internet sites in a shared web hosting account with us, you will be able to activate Varnish with a couple of clicks via your hosting Control Panel. The platform is available as an optional upgrade with all our hosting plans and you can select how many websites will use it and the maximum storage space that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the number of instances and the amount of system memory and they’re not linked directly to each other, so you can decide whether you need plenty of memory for a single large site or less memory for multiple smaller ones. You can use the full potential of the Varnish caching platform if the websites use a dedicated IP address. With the Control Panel, you can easily start/restart/remove an instance, delete the cached content independently for each website which employs Varnish or view an in-depth log.

Varnish in Semi-dedicated Servers

Varnish is a feature, which is included by default with all semi-dedicated servers offered by us and you can use it for workload balancing purposes. It’s available in your Hepsia Control Panel. The Varnish caching platform comes with 64 MB of system memory for cached data storing purposes and you can employ it with any website that you host in your semi-dedicated account. In case you’re in need of more, you can increase the memory quota. The memory itself is available in increments of 32 megabytes in the Control Panel’s Upgrades section. The very same Upgrades section will allow you to enable more instances as well, if you’d like to use the Varnish platform with multiple sites. The two things can be added separately – you can cache the content of a single popular site or run several different sites with the default memory quota. You can take full advantage of the Varnish caching platform in case you use a dedicated IP and you can order one with your semi-dedicated server plan as well. Hepsia will grant you full control over the caching platform and, with no more than one single mouse click, you will be able to clear the cached files, to view a log file or to reboot an instance.

Varnish in Dedicated Servers

In case you order a dedicated server with the Hepsia Control Panel, you’ll acquire the Varnish caching platform at no additional cost and you’ll exert full control over it via an incredibly user-friendly interface – you’ll be able to start, to remove or to restart an instance, to see an in-depth system log, to delete the cache for any site and much, much more. The Varnish platform will have several gigabytes of memory at its disposal, so even if you run traffic-heavy sites with an immense number of visitors, you will notice the much better web page loading speeds and the lowered load on your dedicated server. This will become a fact shortly after you start using Varnish, as it will need a certain amount of time to cache the content that visitors request. You can get the most out of the platform’s capability if the Internet sites that are using it use also a dedicated IP address, but since your dedicated server includes a few IPs by default, you will not have to pay anything on top of the monthly charge for the machine itself.
