Varnish is a web application accelerator platform, which caches data for quicker response times. It is occasionally referred to as an HTTP reverse proxy too and it works between a web server and a browser. When a visitor loads a particular web page, the content is requested by the Internet browser, and then the web server handles this browser request and returns the necessary info. If Varnish is enabled for a particular site, it will cache the pages at the first request and in case the visitor opens a cached page once again, the info will be delivered by the caching platform and not by the web server. The increased load speed is a result of the much faster response time that the Varnish platform offers compared with any server software. Of course, this does not mean that the website visitors will continue being served the very same content over and over again, because any update on any of the web pages is reflected in the content that Varnish keeps in its system memory.
Varnish in Hosting
Varnish comes as an optional upgrade with all our hosting
. You can add it to your website hosting account via the Hepsia hosting Control Panel, which comes with all shared hosting plans and you will get a really easy-to-use GUI, which will grant you complete control over the data caching system. Using one-click fast-access controls, you can reboot or turn off any of the instances, in other words – Varnish will no longer be activated for a certain Internet site. You can also view an elaborate log file or erase the cache associated with any of the sites. When you add Varnish to your hosting plan, you’ll be able to select the maximum amount of memory that will be available to you for data caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 MB and, for maximum performance, you can assign a dedicated IP to the sites that will use Varnish. This will allow you to take full advantage of your sites and to have many happy website visitors.
Varnish in Semi-dedicated Servers
All our semi-dedicated servers
come with Varnish by default, so you can make use of the web application accelerator tool and accelerate the loading speed of any site that you host on our platform. You will get 64 MB of system memory exclusively for Varnish at no extra cost and you can create an instance with no more than a couple of clicks of the mouse from the Hepsia hosting Control Panel, which comes with the semi-dedicated server plans. If you want more memory, the latter is available in increments of 32 megabytes through the Upgrades section of the Control Panel and it will be at your disposal straight away. You can also add more instances as a separate upgrade, so you can decide whether plenty of content will be cached for one site or if the memory will be used by several Internet sites. Hepsia will permit you to restart or to delete any instance, to see the system log associated with it or to clear the cached data using 1-click buttons. To take full advantage of the Varnish accelerator, you can set a dedicated IP for the sites which will use it.
Varnish in Dedicated Servers
In case you order a dedicated server
with the Hepsia hosting Control Panel, you will acquire the Varnish caching platform at no additional fee and you will exert total control over it via a very simple-to-navigate graphical interface – you will be able to start, to terminate or to restart an instance, to check an elaborate system log, to clear the cached files for any website and much more. The Varnish platform will have several GB of system memory at its disposal, so even if you own regularly visited Internet sites with multiple visitors, you will notice the considerably better web page loading speeds and the decreased load on your server. This will become a fact soon after you start using the Varnish platform, since it will need some time to cache the website content that users open. You can take full advantage of the platform’s capability if the Internet sites that are using it also use a dedicated IP, but considering the fact that your dedicated server comes with a couple of IPs by default, you will not need to pay anything on top of the monthly fee for the server itself.
