Varnish is a web accelerator platform, which caches content for the sake of quicker response times. It’s sometimes called an HTTP reverse proxy as well and it interacts between a web server and a web browser. When a website visitor opens a particular page, the content is requested by the browser, and then the web server processes this browser request and sends back the requested info. If Varnish is enabled for a particular website, it will cache its pages at the very first request and in case the visitor visits a cached page for a second time, the data will be delivered by the caching platform and not by the web server. The boosted loading speed is a result of the significantly faster response speed that Varnish offers compared to any web server software. At the same time, this doesn’t mean that the site visitors will keep being served the same content over and over again, because any modification on any of the web pages is reflected in the content that the Varnish platform caches in its memory.
Varnish in Shared Web Hosting
You can unlock Varnish’s full potential and enhance the loading speed of your websites irrespective of the shared web hosting plan that you’ve chosen and you can add and configure the data caching platform with a couple of clicks of the mouse through the easy-to-work-with GUI offered by our next-gen Hepsia hosting Control Panel. In the meantime, you’ll be able to select two separate things – how many sites will employ the Varnish platform, i.e. 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 linked to the number of instances, so you can use more instances and less memory and the other way around. In case you’ve got lots of content on a certain Internet site and you attract lots of site visitors, more memory will give you a better result. You may also consider using a dedicated IP for the websites that will use the Varnish caching platform. The Hepsia Control Panel will provide you with easy 1-click buttons for deactivating or rebooting any instance, for erasing the cache for any Internet site and for seeing comprehensive system logs.
