Varnish is a web accelerator platform, which caches content for the sake of quicker access. It’s occasionally called an HTTP reverse proxy as well and it works between a web server and a web browser. When a visitor opens a specific page, the content is requested by the browser, and then the server handles this request and returns the necessary content. If Varnish is activated for a given website, it will cache the pages on the very first visit and in case the user visits a cached page once more, the information will be delivered by the accelerator platform and not by the server. The boosted load speed is a result of the much faster response time that Varnish offers compared to any web server software. Of course, this doesn’t mean that the users will keep seeing the exact same content over and over again, because any modification on any of the pages is reflected in the content that Varnish stores in its system memory.
Varnish in Cloud Website Hosting
You can unlock Varnish’s potential and increase your sites’ load speed regardless of the cloud website hosting package that you’ve selected and you can activate and configure the content caching platform with several clicks of the mouse from the easy-to-use graphical interface offered by our advanced Hepsia Control Panel. In the meantime, you’ll be able to choose two different things – how many websites will employ the Varnish caching platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of memory. The latter comes in increments of 32 MB and is not bound to the number of instances, so you can use more instances and less memory and the other way around. If you have plenty of content on a certain site and you receive a lot of website visitors, more system memory will give you a better result. You may also consider employing a dedicated IP for the sites that will use the Varnish platform. Hepsia will offer you simple one-click buttons for shutting down or rebooting any instance, for deleting the cache for any website and for viewing elaborate system logs.
Varnish in Semi-dedicated Hosting
Varnish is part of the basic service set that you’ll receive if you choose to host your sites in a semi-dedicated server account. You can enable it for any of your sites through our leading-edge Hepsia Control Panel. The default memory that the Varnish platform can use to cache data is 64 megabytes, but in case you decide that you want 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 Internet sites that can use this platform at the same time. As these two features are not bound to each other, you can use a few Internet sites with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for one single website. The Varnish caching platform works best if you use a dedicated IP for the websites that utilize its power. The Hepsia Control Panel will provide you with an easy way of restarting any instance. Also, you’ll be able to clear the cached contents with just a click.
Varnish in Dedicated Web Hosting
All Linux dedicated servers hosting packages that are ordered with the custom-developed Hepsia hosting Control Panel include 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 effortlessly through the Hepsia Control Panel’s user-friendly GUI and, with no more than one mouse click, you can view an exhaustive log, create or reboot an instance, clear the cached data for any Internet site and much more. Soon after you set up the Varnish platform for a specific domain or subdomain, it will begin caching the pages accessed by your website visitors and once it has cached enough web content, you’ll observe a tremendously better site performance in addition to a lowered load on the machine. With Varnish-dedicated virtual memory starting at 3 GB, you will be able to use the platform for load distribution purposes even if you host numerous sites on your dedicated server.
