Varnish can considerably raise the general performance of your sites. Learn how to make the most of its power.
Varnish is a web app accelerator platform, which caches information for the sake of quicker access. It’s sometimes called a caching HTTP reverse proxy as well and it interacts between a web server and a web browser. When a website visitor loads a certain page, the content is requested by the web browser, and then the server handles this browser request and delivers the needed data. If Varnish is activated for a certain website, it will cache its pages on the first request and in case the visitor visits a cached page for a second time, the content will be delivered by the caching platform instead of the server. The improved speed is an end result of the significantly faster response speed that the Varnish platform offers compared with any web server software. Of course, this doesn’t mean that the visitors will keep seeing the same content over and over again, as any change on any of the web pages is reflected in the content that Varnish caches in its system memory.
Varnish in Hosting
Varnish comes as an optional upgrade with each of our hosting plans. You can add it to your web hosting account from the Hepsia Control Panel, which is available with all shared packages and you’ll get an amazingly easy-to-use graphical interface, which will give you complete control over the content caching platform. Using one-click fast-access buttons, you can reboot or remove any of the instances, i.e. Varnish will no longer be enabled for a specific website. You can also see an exhaustive system log or clear the cache associated with any of the websites. When you add Varnish to your hosting plan, you’ll be able to choose the maximum amount of system memory that will be at your disposal for caching purposes and the number of the sites that will use Varnish. You can always add more memory in increments of 32 megabytes and, for optimal performance, you can assign a dedicated IP address to the websites that will use Varnish. This will permit you to take full advantage of your sites and to have numerous gratified website users.
