Varnish is a web app accelerator platform, which caches content for faster response times. It is occasionally referred to as an HTTP reverse proxy as well and it works between a web server and a web browser. When a visitor opens a specific web page, the content is requested by the Internet browser, and then the web server processes this request and returns the needed data. If Varnish is enabled for a certain website, it will cache the pages at the first request and in case the visitor opens a cached page for a second time, the information will be delivered by the accelerator platform and not by the server. The boosted speed is a result of the significantly faster response time that Varnish offers compared with any server software. At the same time, this does not mean that the users will keep seeing the very same content again and again, since any modification on any of the web pages is reflected in the content that Varnish stores in its system memory.

Varnish in Cloud Web Hosting

If you host your websites under a cloud web hosting account with our company, you’ll be able to add Varnish with a few clicks of the mouse from your hosting Control Panel. The data caching platform comes as an upgrade with all our shared hosting packages and you can select the number of the sites that will use it and the maximum amount of system memory that will be used for the cached content. The two upgradeable features in the Control Panel’s Upgrades section are the amount of system memory and the number of instances and they aren’t tied directly to each other, so you can decide whether you need lots of memory for one single large website or less memory for multiple smaller ones. You can use the full potential of the Varnish platform if the websites use a dedicated IP address. Using the hosting Control Panel, you can quickly start/restart/disable an instance, delete the cached content individually for each website that employs Varnish or check a comprehensive log file.

Varnish in Semi-dedicated Servers

The Varnish caching platform is included in the default service set that you’ll obtain if you decide to host your Internet sites in a semi-dedicated server account. You can activate it for any of your Internet sites via our leading-edge Hepsia hosting Control Panel. The default system memory that Varnish can use to cache content is 64 megabytes, but in case you decide that you need more, you can upgrade this amount from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, in other words – the number of the sites that can use this caching platform simultaneously. Since these two things aren’t bound to each other, you can use a few websites with the default memory or you can get more memory in increments of 32 MB and use all of it for a single website. Varnish performs best when you allocate a dedicated IP address to the Internet sites that utilize its power. Hepsia will offer you an easy means of restarting any instance. Furthermore, you will be able to delete the cached content with only one mouse click.

Varnish in Dedicated Servers

All dedicated web hosting plans that are ordered with the in-house built Hepsia website hosting Control Panel feature Varnish, which is one of the pre-installed software platforms that you will get with the machine. The Varnish caching platform can be enabled and managed with no effort from the Hepsia Control Panel’s intuitive interface and, with no more than one click of the mouse, you can see a detailed system log, add or reboot an instance, delete the cached data associated with any site and much more. Shortly after you enable Varnish for a given domain or sub-domain, it will start caching the web pages accessed by your visitors and once it has cached enough web content, you will perceive a considerably faster site performance plus a lowered load on your server. With Varnish-dedicated system memory starting at three gigabytes, you will be able to use the platform for load distribution purposes even if you host multiple websites on your machine.
