Learn about Varnish, understand more details on web accelerators and see what it really is that they can do.
Varnish is a website accelerator platform, which caches info for the sake of faster access. It’s occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and a browser. When a website visitor opens a given webpage, the content is requested by the Internet browser, and then the server handles this browser request and sends back the required info. If Varnish is enabled for a website, it will cache the pages at the first visit and if the user visits a cached page once again, the data will be delivered by the accelerator platform and not by the web server. The increased load speed is a result of the much faster response time that Varnish offers compared with any server software. Of course, this does not mean that the website visitors will continue seeing the very same content again and again, because any change on any of the web pages is reflected in the content that Varnish saves in its system memory.
Varnish in Shared Hosting
Varnish is offered as an optional upgrade with all our Linux shared service
. You can add it to your web hosting account from the Hepsia Control Panel, which is available with all shared web hosting plans and you will get a rather user-friendly interface, which will give you complete control over the content caching platform. Using one-click quick-access controls, you can restart or stop any of the instances, in other words – Varnish will no longer work for a certain Internet site. You can also check a detailed log or delete the cache associated with any of the sites. When you add Varnish to your shared web hosting plan, you will be able to choose the total amount of memory that will be available to you for content caching purposes and the number of the sites that will use Varnish. You can always get more memory in increments of 32 megabytes and, for maximum performance, you can get a dedicated IP for the websites that will use Varnish. This will permit you to get the most out of your Internet sites and to have plenty of pleased visitors.
Varnish in Semi-dedicated Servers
The semi-dedicated servers
offered by us will permit you to use Varnish once your brand new account has been opened, since the data caching platform comes by default. 64 MB of system memory will be allocated to Varnish the moment your account is enabled, so you can make use of this load balancing software as soon as your website has been published on the Internet. In case you need more memory, you can get 32 megabytes at a time from the Upgrades section of the Hepsia hosting Control Panel and it will be allocated to your semi-dedicated machine momentarily. You can also increase the number of the sites that employ Varnish, or the so-called ‘instances’, which are not linked directly to the amount of system memory that you use, which means that you’ll enjoy more versatility. The caching platform will enormously lower the server load that your sites cause, so your visitors can enjoy fast-loading pages. You will be able to manage Varnish effortlessly through your Hepsia Control Panel using fast-access controls.

Varnish in VPS Servers
You can use the workload balancing potential of Varnish with all our VPS servers
if you pick Hepsia as your web hosting Control Panel. The Varnish data caching platform comes by default and the amount of memory that it will be able to utilize to cache the content of your sites is dependent on the particular Virtual Private Server package that you have chosen, but even with the lower-end packages, you’ll have at least several hundred MB of memory at your disposal solely for content caching purposes. This amount is enough to improve the overall performance of numerous Internet sites. It will take some time for you to notice the effects, as Varnish caches the content that site visitors open, but shortly thereafter you’ll notice the significantly decreased load on your VPS and the improved website browsing speed. The Varnish platform will allow you to use a lower-end Virtual Private Server plan for websites that would normally need a more high-priced web hosting service.
