Varnish is a web app accelerator platform, which caches data for the sake of quicker response times. It’s sometimes called a caching HTTP reverse proxy too and it works between a web server and a browser. When a visitor loads a specific web page, its content is requested by the web browser, and then the web server handles this browser request and sends back the requested info. If Varnish is activated for a certain site, it will cache the pages at the very first request and in case the visitor opens a cached page for a second time, the information will be delivered by the caching platform instead of the server. The accelerated load speed is an end result of the significantly faster response speed that Varnish offers compared to any web server software. Of course, this doesn’t mean that the users will continue being served the exact same content over and over again, because any modification on any of the pages is reflected in the content that the Varnish platform caches in its system memory.
Varnish in Web Hosting
Varnish is available as an optional upgrade with all our web hosting
. You can add it to your website hosting account from the Hepsia hosting Control Panel, which is available with all shared plans and you’ll get a rather easy-to-use graphical interface, which will give you complete control over the caching platform. Using one-click fast-access buttons, you can reboot or discontinue any of the instances, i.e. Varnish will no longer be enabled for a certain site. You can also see an exhaustive log file or erase the cache associated with any of the Internet sites. When you add Varnish to your shared hosting package, you’ll be able to select the maximum amount of system memory that will be at your disposal for content caching purposes and how many websites will use Varnish. You can always get more memory in increments of 32 MB and, for top performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will permit you to take full advantage of your websites and to have numerous happy users.
