Varnish is a web application accelerator platform, which caches content for the sake of quicker response times. It’s occasionally called a caching HTTP reverse proxy as well and it interacts between a web server and its users. When a site visitor opens a particular webpage, the content is requested by the web browser, and then the web server processes this request and delivers the required information. If Varnish is enabled for a given site, it will cache the pages at the first request and in case the visitor visits a cached page once more, the info will be delivered by the caching platform and not by the server. The improved speed is an end result of the substantially faster response speed that Varnish offers compared with any server software. At the same time, this does not mean that the site visitors will keep being served the exact same content again and again, because any change on any of the web pages is reflected in the content that Varnish saves in its system memory.
Varnish in Shared Web Hosting
You can use Varnish’s full potential and accelerate your sites irrespective of the shared web hosting plan that you’ve picked and you can activate and set up the data caching platform with a few clicks of the mouse via the easy-to-use interface offered by our avant-garde Hepsia Control Panel. In the meantime, you will be able to select two separate things – how many Internet sites will employ the Varnish caching platform, in other words – the number of instances, and how much data will be cached, i.e. the amount of system memory. The latter is available in increments of 32 MB and is not linked to the number of instances, so you can add more instances with less memory and the other way around. If you’ve got a lot of content on a particular Internet site and you win numerous website visitors, more system memory will give you a better result. You may also consider using a dedicated IP address for the websites that will use the Varnish platform. Hepsia will offer you simple 1-click buttons for stopping or restarting any instance, for deleting the cache associated with any site and for viewing comprehensive system logs.
