Discover Varnish, understand more details on website accelerators and see what it really is that they can do.
Varnish is a web accelerator platform, which caches information for faster access. It’s occasionally referred to as an HTTP reverse proxy too and it interacts between a web server and its users. When a visitor accesses a certain webpage, the content is requested by the Internet browser, and then the server handles this request and delivers the necessary content. If Varnish is enabled for a certain site, it will cache the pages on the first request and in case the visitor accesses a cached page once more, the information will be delivered by the caching platform and not by the server. The accelerated loading speed is a result of the significantly faster response time that Varnish offers compared with any web server software. Of course, this does not mean that the visitors will keep seeing the exact same content again and again, as any change on any of the pages is reflected in the content that Varnish caches in its memory.
Varnish in Shared Website Hosting
Varnish is offered as an optional upgrade with each of our Linux shared website hosting packages
. You can add it to your web hosting account from the Hepsia hosting Control Panel, which comes with all shared plans and you will get a quite easy-to-work-with graphical interface, which will give you full control over the content caching system. Using one-click quick-access buttons, you can restart or shut down any of the instances, i.e. Varnish will no longer work for a specific Internet site. You can also see a comprehensive system log file or erase the cache for any of the Internet sites. When you add Varnish to your shared hosting package, you will be able to select the maximum amount of system memory that will be available to you for content caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 MB and, for optimum performance, you can assign a dedicated IP address to the sites that will use Varnish. This will enable you to get the most out of your websites and to have numerous happy site visitors.
Varnish in Semi-dedicated Hosting
The Varnish content caching platform is included in the standard service set that you’ll acquire in case you choose to host your sites in a semi-dedicated server
account. You can enable it for any of your websites via our advanced Hepsia Control Panel. The default amount of memory that the Varnish caching platform can use to cache content 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 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 several instances with the default amount of memory or you can add more memory in increments of 32 megabytes and use all of it for one single site. The Varnish platform works best when you set a dedicated IP for the websites that utilize its power. The Hepsia Control Panel will offer you an easy means of restarting any instance. What’s more, you will be able to clear the cached contents with only one single click of the mouse.
Varnish in VPS Hosting
We offer Varnish with all of the Hepsia-equipped Linux VPS hosting packages
, so if you get a server with this hosting Control Panel, you will be able to make the most of the caching platform at no extra charge. The Varnish platform can use different amounts of memory for content caching purposes based on the very sever setup that you’ve chosen during the registration process, but nevertheless, this amount won’t be less than several hundred megabytes. This is more than enough to optimize the overall performance of several different busy Internet sites, so the better web page loading speeds and the decreased load on the VPS server will be perceivable. The result may not be observable instantly, since the Varnish platform will need some time to cache the website content that users browse, but shortly after you activate it, you will witness its full capacity. This platform will permit you to use a less powerful Virtual Private Server and to give less money to get the very same performance you would get with a higher-end machine without Varnish.
Varnish in Dedicated Web Hosting

which are ordered with the custom Hepsia hosting Control Panel come with Varnish, which is among the pre-installed platforms that you will get with the dedicated server.

With Varnish-dedicated system memory starting at 3 GB, you’ll be able to use the platform for load distribution purposes even if you run a vast number of websites on your machine.
