Varnish is a web app accelerator platform, which caches info for faster access. It’s sometimes called an HTTP reverse proxy as well and it interacts between a web server and its users. When a site visitor loads a certain web page, its content is requested by the web browser, and then the web server processes this browser request and sends back the necessary info. If Varnish is enabled for a certain site, it will cache its pages on the very first visit and if the user accesses a cached page for a second time, the data will be delivered by the caching platform instead of the server. The improved loading speed is a result of the much faster response time that the Varnish platform offers compared to any web server software. Of course, this does not mean that the site visitors will continue being served the same content again and again, as any change on any of the web pages is reflected in the content that Varnish saves in its memory.

Varnish in Shared Hosting

Varnish is available as an optional upgrade with each of our shared hosting plans. You can add it to your account through the Hepsia Control Panel, which is available with all shared packages and you’ll get a really easy-to-use interface, which will give you full control over the caching system. Using 1-click quick-access controls, you can reboot or disable any of the instances, in other words – Varnish will no longer be activated for a certain site. You can also see a detailed system log file or clear the cache for any of the Internet sites. When you add Varnish to your shared web hosting plan, you will be able to choose the maximum amount of system memory that will be available to you for caching purposes and the number of the sites that will use Varnish. You can always order more memory in increments of 32 megabytes and, for optimal performance, you can assign a dedicated IP address to the websites that will use Varnish. This will enable you to get the most out of your websites and to have many satisfied users.

Varnish in Semi-dedicated Servers

The Varnish platform is included in the default set of services that you’ll obtain in case you choose to host your sites in a semi-dedicated server account. You can set it up for any of your Internet sites via our next-generation Hepsia Control Panel. The default amount of memory that the Varnish platform can use to cache data is 64 MB, but if you decide that you need more, you can upgrade this amount 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 caching platform simultaneously. As these two things aren’t bound to each other, you can use a couple of instances with the default amount of memory or you can order more memory in increments of 32 MB and use all of it for a single website. Varnish works best when you assign a dedicated IP to the sites that utilize its power. Hepsia will offer you an easy way of restarting any instance. Furthermore, you will be able to delete the cached contents with just one single mouse click.

Varnish in Dedicated Servers

You can use Varnish to optimize the loading speed of any site that is hosted on a dedicated server from us when the Hepsia hosting Control Panel is pre-installed on the machine. Not only will you get the caching platform ready to be used at no additional charge, but you will also have total control over it through Hepsia’s user-friendly interface. It’ll take just one click of the mouse to start or disable an instance or to clear the cached files associated with any website that’s using the Varnish platform and if you are more tech-savvy, you can also browse the platform’s system logs. Varnish comes with at least three gigabytes of virtual memory for website content caching purposes, so even if you host a large number of sites on your dedicated server and they all use the Varnish platform, the improvement in their performance will be obvious. You will simply need to wait for a little while till Varnish caches whatever content the website visitors browse on their end. The Varnish platform performs best when the websites use a dedicated IP address, but owing to the fact that our servers come with 3 free IPs, you’ll have all that you need.
