Varnish is a web accelerator platform, which caches info for faster response times. It is sometimes called a caching HTTP reverse proxy too and it works between a web server and a web browser. When a website visitor loads a particular page, the content is requested by the Internet browser, and then the server handles this request and sends back the requested information. If Varnish is enabled for a particular site, it will cache its pages on the very first request and in case the user opens a cached page for a second time, the data will be delivered by the accelerator platform instead of the server. The increased speed is an end result of the significantly faster response time that the Varnish platform offers compared with any server software. At the same time, this does not mean that the users will continue being served the same content over and over again, as any change on any of the pages is reflected in the content that Varnish keeps in its system memory.

Varnish in Shared Website Hosting

If you host your sites in a shared website hosting account with our company, you will be able to activate Varnish with a few clicks of the mouse via your Control Panel. The caching platform comes as an optional upgrade with all our shared plans and you can choose how many websites will use it and the total amount of system memory that will be available for the cached data. The two upgradeable features in the Upgrades section of the Control Panel are the amount of system memory and the number of instances and they’re not directly tied to each other, so you can choose if you need a lot of memory for one large site or less memory for several smaller ones. You can make use of the full potential of the Varnish caching platform if the websites use a dedicated IP. Using the hosting Control Panel, you can swiftly start/reboot/deactivate an instance, delete the cached contents independently for each site that uses Varnish or see a comprehensive system log.

Varnish in Semi-dedicated Servers

The Varnish caching platform is included in the basic set of services that you will obtain when you decide to host your Internet sites in a semi-dedicated server account. You can enable it for any of your sites through our next-generation Hepsia hosting Control Panel. The default system memory that the Varnish caching platform can use to cache data is 64 megabytes, but if you decide that you want more, you can upgrade this memory from the Upgrades section of the Control Panel. You can also upgrade the Varnish instances, i.e. the number of the websites that can use this platform simultaneously. Since these two things aren’t bound to each other, you can use a few instances with the default memory or you can add more memory in increments of 32 MB and use all of it for one single web site. Varnish works best if you set a dedicated IP for the sites that utilize its power. Hepsia will give you an easy means of restarting any instance. Also, you’ll be able to delete the cached data with just one click.

Varnish in Dedicated Servers

All dedicated servers that are ordered with the custom Hepsia website hosting Control Panel include Varnish, which is one of the pre-installed platforms that you’ll get with the machine. The Varnish caching platform can be activated and administered effortlessly from the Hepsia Control Panel’s easy-to-work-with graphical interface and, with no more than one single mouse click, you can browse a comprehensive system log, create or reboot an instance, delete the cached data associated with any website and much, much more. Soon after you set up the Varnish platform for a particular domain or sub-domain, it will begin caching the web pages requested by your site visitors and as soon as it has cached enough content, you will observe a considerably faster website performance in addition to a decreased load on your dedicated server. With Varnish-dedicated virtual memory starting at 3 gigabytes, you’ll be able to use the platform for load distribution purposes even if you run many websites on your server.
