Varnish is a web application accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, at times even by 100%, depending on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to decrease the overall server load and to accelerate the browsing speed for the website visitors. Whenever a visitor accesses a page on a certain Internet site, the web browser request is processed by the web server and the requested content is served as a response. If Varnish is enabled, it caches the pages that the website visitor browses and if any of them is accessed once again, it is fetched by Varnish and not by the server directly. The performance improvement comes from the fact that the accelerator processes the web requests substantially faster than any web server, which leads to much faster browsing speeds for the users. In case any data is updated meanwhile, the cached web pages will also be ‘refreshed’ the next time somebody tries to open them.
Varnish in Shared Hosting
You can use Varnish’s potential and accelerate your websites’ load speed regardless of the shared hosting
plan that you’ve selected and you can add and configure the content caching platform with a couple of mouse clicks from the simple-to-use graphical interface offered by our next-generation Hepsia Control Panel. During the procedure, you will be able to select two separate things – how many Internet sites will use the Varnish platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of system memory. The latter comes in increments of 32 megabytes and is not bound to the number of instances, so you can add more instances and less memory and vice versa. If you’ve got plenty of content on a given Internet site and you attract a lot of site visitors, more memory will guarantee you better results. You may also consider using a dedicated IP for the sites that will use the Varnish caching platform. Hepsia will provide you with easy 1-click buttons for disabling or restarting any instance, for erasing the cache for each website and for seeing in-depth logs.
Varnish in Semi-dedicated Servers
Varnish is a feature, which is included by default with all semi-dedicated plans
offered by us and you can use it for load balancing purposes. It is available in your Hepsia hosting Control Panel. The Varnish data caching platform comes with 64 megabytes of system memory for cached content storing purposes and you can employ it with any Internet site that you host in the semi-dedicated server account. If you are in need of more than that, you can increase the memory quota. The memory itself is available in increments of 32 megabytes through the Upgrades section of the Control Panel. The same section will permit you to create more instances too, in case you would like to use Varnish with multiple sites. The two things can be added independently – you can cache the content of one large-sized Internet site or run several sites with the default memory allowance. You can take full advantage of Varnish if you have a dedicated IP and you can order one with your semi-dedicated package as well. Hepsia will give you full control over the caching platform and, with no more than one single click, you will be able to clear the cached files, to view a system log file or to restart an instance.
Varnish in Dedicated Servers
You can use Varnish in order to enhance the loading speed of any website that’s hosted on a dedicated server
with us when the Hepsia hosting Control Panel is installed on the machine. Not only will you get the platform ready for use at no extra cost, but you will also exert full control over it through Hepsia’s easy-to-navigate GUI. It’ll take just one single click of the mouse to start or remove an instance or to delete the cached content associated with any Internet site that’s using Varnish and if you’re more practiced, you can also check the platform’s system logs. Varnish comes with at least 3 GB of virtual memory for site content caching purposes, so even if you run numerous websites on your machine and they all use the platform, the improvement in their overall performance will be evident. You’ll just need to wait for a while until Varnish caches whatever content the website visitors browse on their end. The platform performs best when the sites use a dedicated IP address, but due to the fact that our servers come with three free IPs, you will have all that you need.
