Varnish is a web app accelerator platform, which caches info for the sake of quicker response times. It is occasionally called an HTTP reverse proxy as well and it works between a web server and an Internet browser. When a site visitor loads a certain page, the content is requested by the Internet browser, and then the server handles this browser request and delivers the needed info. If Varnish is activated for a certain site, it will cache the pages at the very first request and if the user visits a cached page for a second time, the content will be delivered by the caching platform and not by the server. The accelerated load speed is an end result of the considerably faster response speed that Varnish offers compared with any server software. At the same time, this does not mean that the visitors will continue seeing the very same content over and over again, because any change on any of the web pages is reflected in the content that the Varnish platform stores in its memory.
Varnish in Web Hosting
Varnish is offered as an optional upgrade with each of our Linux web hosting
. You can add it to your account through the Hepsia Control Panel, which comes with all shared hosting plans and you’ll get a rather easy-to-use GUI, which will give you full control over the data caching platform. Using one-click fast-access buttons, you can restart or remove any of the instances, i.e. Varnish will no longer be activated for a given Internet site. You can also see a detailed system log file or erase the cache associated with any of the sites. When you add Varnish to your shared hosting package, you will be able to select the total amount of memory that will be available to you for data caching purposes and how many sites will use Varnish. You can always add more memory in increments of 32 MB and, for optimum performance, you can assign a dedicated IP to the sites that will use Varnish. This will allow you to take full advantage of your sites and to have a lot of gratified visitors.
