Discover Varnish, understand more details on web accelerators and find out exactly what is they do.
Varnish is a web application accelerator tool, which has been gaining a lot of popularity lately, because it can increase the speed of any Internet site, sometimes even by one hundred percent, depending on the content. This tool is sometimes referred to as a caching HTTP reverse proxy too and is used to reduce the overall load on the physical server and to accelerate the browsing speed for the website visitors. Each time a visitor loads a page on a particular site, the web browser request is taken care of by the web server and the requested data is delivered as a response. If the Varnish accelerator is enabled, it caches the web pages that the visitor browses and if any of them is opened once again, it’s fetched by Varnish and not by the web server directly. The increase in the overall performance comes from the fact that the accelerator processes the browser requests substantially quicker than any web server, which leads to much faster browsing speeds for the visitors. If any data is edited in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody attempts to open them.
Varnish in Hosting
You can make use of Varnish’s full potential and boost the loading speed of your sites regardless of the hosting plan that you have picked and you can activate and configure the data caching platform with several mouse clicks using the simple-to-use GUI offered by our avant-garde Hepsia hosting Control Panel. During the procedure, you’ll be able to choose two different things – how many Internet sites will use the Varnish platform, in other words – 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 megabytes and is not linked to the number of instances, so you can add more instances and less memory and the other way around. If you have lots of content on a particular Internet site and you attract numerous website visitors, more system memory will guarantee you a better result. You may also consider using a dedicated IP for the Internet sites that will use Varnish. Hepsia will provide you with easy 1-click controls for discontinuing or restarting any instance, for deleting the cache associated with each Internet site and for checking detailed system logs.
