Varnish is a data caching platform, which is occasionally called a caching HTTP reverse proxy. It is a web application accelerator tool that can increase the load speed of a site by up to 1000 percent, based on its content. Anytime a visitor accesses any page on a website that uses Varnish, the platform caches the page and delivers it instead of the web server if the visitor loads it again. In this way, the browser request from the visitor is not handled by the server and the web page will open considerably faster, since the Varnish platform can deliver information many times faster than any web server software. The end result will be a significantly faster loading page, which leads to an enormously improved visitor experience. When any of the cached webpages is updated on the actual site, the data that Varnish caches in its memory is ‘refreshed’ too, so the users will never see old data.
Varnish in Shared Hosting
Varnish comes as an optional upgrade with each shared hosting and if you wish to use it, you can add it to your shared account using the Upgrades menu in your Hepsia Control Panel. There are two different features that can be upgraded – the number of instances and the memory. The first one refers to the number of the Internet sites that you wish to use Varnish for and the second one, which comes in increments of 32 megabytes, displays the maximum amount of content that the content caching platform can cache at any particular moment. The Hepsia Control Panel’s time and effort saving interface will enable you to delete or to reboot any instance, to see in-depth system logs or to erase the platform’s cache with just click of the mouse. For optimum results, you can employ a dedicated IP address for the websites that will use the caching platform. With Varnish, your Internet site will open substantially faster, meaning more happy users and potential customers.
