Varnish is a content caching platform, which is occasionally called a caching HTTP reverse proxy. It’s a web app accelerator tool that can accelerate the load speed of a site by up to one thousand percent, based on the content itself. Each time a visitor accesses any page on a site that uses Varnish, the platform caches the page and delivers it instead of the web server when the visitor accesses it again. Thus, the web browser request from the visitor is not processed by the web server and the page will open much faster, since the Varnish platform can serve data many times faster than any server software. The result will be a substantially faster loading site, which means an improved website browsing experience. If any of the cached web pages is updated on the actual site, the data that Varnish saves in its system memory is updated too, so the visitors will never end up seeing out-of-date content.
Varnish in Hosting
You can unlock Varnish’s potential and increase your sites’ loading speed irrespective of the hosting package that you’ve chosen and you can enable and set up the content caching platform with several mouse clicks via the simple-to-work-with GUI offered by our innovative Hepsia hosting Control Panel. In the meantime, you will be able to select two separate 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 available in increments of 32 MB and is not bound to the number of instances, so you can add more instances with less memory and the other way around. In case you’ve got a lot of content on a given Internet site and you attract plenty of visitors, more memory will give you a better result. You may also consider employing a dedicated IP address for the Internet sites that will use the Varnish platform. The Hepsia Control Panel will offer you easy one-click buttons for switching off or rebooting any instance, for erasing the cache for any Internet site and for checking elaborate logs.
