Varnish is a data caching platform, which is sometimes called a caching HTTP reverse proxy. It’s a web accelerator tool that can increase the loading speed of a website by up to one thousand percent, based on its content. Anytime a visitor opens any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server in case the visitor accesses it again. In this way, the web browser request from the visitor is not handled by the server and the web page will open considerably faster, as Varnish can serve content many times faster than any web server software. The end result will be a considerably faster loading site, which means an enormously improved website browsing experience. If any of the cached web pages is updated on the actual Internet site, the information that Varnish caches in its memory is updated too, so the users will never end up seeing old info.
Varnish in Cloud Website Hosting
You can unleash Varnish’s full potential and enhance the load speed of your sites irrespective of the cloud website hosting
package that you have selected and you can add and configure the content caching platform with a couple of clicks of the mouse from the simple-to-use graphical interface offered by our next-generation Hepsia Control Panel. In the meantime, you will be able to choose two different things – how many Internet sites will use Varnish, in other words – the number of instances, and how much data will be cached, in other words – the amount of system memory. The latter is offered in increments of 32 megabytes and is not tied to the number of instances, so you can use more instances with less memory and the other way around. If you have lots of content on a certain Internet site and you gain plenty of visitors, more memory will give you a better result. You may also consider using a dedicated IP address for the websites that will use Varnish. The Hepsia Control Panel will offer you easy 1-click controls for turning off or rebooting any instance, for erasing the cache associated with each Internet site and for viewing in-depth system logs.
