Varnish is a data caching platform, which is sometimes called an HTTP reverse proxy. It’s a web application accelerator that can improve the loading speed of a website by up to one thousand percent, depending on the content itself. Each time a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor opens it again. Thus, the web browser request from the visitor is not processed by the server and the web page will load considerably faster, since the Varnish platform can deliver information many times faster than any server software. The end result is a considerably faster loading website, which leads to an immensely improved visitor experience. If any of the cached web pages is updated on the actual Internet site, the content that Varnish stores in its system memory is updated too, so the website visitors will never end up seeing old data.
Varnish in Shared Website Hosting
You can take advantage of Varnish’s full potential and accelerate the loading speed of your sites irrespective of the shared website hosting plan that you have selected and you can activate and set up the content caching platform with a few clicks of the mouse using the simple-to-use graphical interface offered by our innovative Hepsia hosting Control Panel. During the process, you will be able to select two different things – how many websites will employ the Varnish platform, i.e. the number of instances, and how much content will be cached, in other words – the amount of system memory. The latter comes in increments of 32 MB and is not linked to the number of instances, so you can order more instances and less memory and the other way around. If you have lots of content on a particular Internet site and you receive many website visitors, more system memory will give you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use Varnish. Hepsia will provide you with easy 1-click controls for disabling or restarting any instance, for clearing the cache associated with each Internet site and for checking detailed logs.
