Varnish is a website accelerator platform, which caches content for the sake of faster response times. It’s occasionally called a caching HTTP reverse proxy too and it works between a web server and its users. When a website visitor opens a given page, the content is requested by the browser, and then the server handles this browser request and sends back the needed data. If Varnish is enabled for a particular website, it will cache the pages on the first visit and if the user opens a cached page for a second time, the information will be delivered by the accelerator platform and not by the web server. The accelerated speed is a result of the considerably faster response time that Varnish offers compared to any web server software. At the same time, this does not mean that the website visitors will keep being served the same content over and over again, since any update on any of the web pages is reflected in the content that Varnish stores in its system memory.
Varnish in Cloud Web Hosting
You can unleash Varnish’s full potential and optimize the loading speed of your websites irrespective of the cloud web hosting plan that you have picked and you can activate and configure the content caching platform with several mouse clicks from the user-friendly interface offered by our next-gen Hepsia Control Panel. During the procedure, you’ll be able to select two separate things – how many websites will use the Varnish caching platform, i.e. the number of instances, and how much info will be cached, in other words – the amount of memory. The latter comes in increments of 32 megabytes and is not linked to the number of instances, so you can add more instances with less memory and vice versa. In case you’ve got lots of content on a particular Internet site and you win numerous site visitors, more system memory will give you better results. You may also consider using a dedicated IP for the Internet sites that will use the Varnish platform. Hepsia will offer you easy one-click buttons for deleting or restarting any instance, for clearing the cache for each site and for seeing in-depth system logs.
