Varnish
Learn just what Varnish is. Discover more about web accelerators and their role.
Varnish is a web app accelerator platform, which caches info for the sake of faster access. It is occasionally called an HTTP reverse proxy too and it interacts between a web server and a web browser. When a website visitor accesses a specific page, its content is requested by the browser, and then the server handles this request and sends back the needed information. If Varnish is enabled for a specific site, it will cache the pages on the very first request and if the user visits a cached page for a second time, the info will be delivered by the caching platform instead of the web server. The boosted speed is an end result of the considerably faster response speed that the Varnish platform offers as compared with any server software. At the same time, this doesn’t mean that the users will keep seeing the same content again and again, because any modification on any of the pages is reflected in the content that Varnish caches in its memory.

Varnish in Shared Hosting
You can take advantage of Varnish’s potential and accelerate the load speed of your sites regardless of the
shared hosting package that you have picked and you can enable and configure the platform with a couple of mouse clicks through the user-friendly GUI offered by our cutting-edge Hepsia hosting Control Panel. During the process, you’ll be able to select two different things – how many sites will use the Varnish caching platform, in other words – the number of instances, and how much data will be cached, i.e. 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 use more instances and less memory and the other way around. In case you have plenty of content on a specific Internet site and you get lots of website visitors, more system memory will guarantee you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish caching platform. Hepsia will offer you simple 1-click controls for cancelling or rebooting any instance, for deleting the cache associated with any site and for seeing in-depth system logs.

Varnish in Semi-dedicated Hosting
The Varnish platform is an essential part of the default service set that you will get when you choose to host your Internet sites under a
semi-dedicated server account. You can configure it for any of your Internet sites through our leading-edge Hepsia Control Panel. The default system memory that Varnish can use to cache data is 64 megabytes, but if you decide that you need more, you can upgrade this memory from the Control Panel’s Upgrades section. You can also upgrade the Varnish instances, in other words – the number of the Internet sites that can use this caching platform at the same time. Since these two things aren’t bound to each other, you can use a couple of websites with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for a single web site. Varnish works best when you set a dedicated IP address for the Internet sites that utilize its power. The Hepsia Control Panel will provide you with an easy means of restarting any instance. What’s more, you’ll be able to delete the cached content with just one click.

With Varnish-dedicated memory starting at three gigabytes, you will be able to use the platform for workload distribution purposes even if you host numerous sites on the dedicated machine.
