Varnish is a web accelerator tool, which has been gaining a lot of popularity in recent years, as it can increase the load speed of any website, sometimes even by 100%, depending on the content itself. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the server and to increase the browsing speed for the site visitors. Every time a visitor loads a page on a particular website, the browser request is handled by the web server and the requested info is served as a reply. If Varnish is enabled, it caches the web pages that the visitor opens and in case any of them is loaded once again, it is delivered by Varnish and not by the server directly. The improvement in the performance comes from the fact that the accelerator handles the browser requests considerably quicker than any web server, which results in much faster browsing speeds for the website visitors. If any data is edited in the meantime, the cached pages will also be ‘refreshed’ the next time somebody tries to open them.
Varnish in Shared Hosting
You can use Varnish’s potential and improve your websites’ load speed irrespective of the shared hosting package that you have selected and you can add and set up the data caching platform with several mouse clicks from the user-friendly graphical interface offered by our cutting-edge Hepsia Control Panel. In the meantime, you will be able to select two different things – how many Internet sites will employ the Varnish caching platform, in other words – the number of instances, and how much info will be cached, i.e. the amount of memory. The latter comes in increments of 32 MB and is not linked to the number of instances, so you can use more instances with less memory and the other way around. If you have a lot of content on a particular site and you draw a lot of site visitors, more memory will give you better results. You may also consider using a dedicated IP for the sites that will use the Varnish caching platform. Hepsia will offer you easy 1-click buttons for removing or restarting any instance, for clearing the cache associated with any website and for viewing elaborate system logs.
