Varnish is a website accelerator platform, which caches info for the sake of faster response times. It’s sometimes called a caching HTTP reverse proxy as well and it works between a web server and its users. When a visitor accesses a given webpage, its content is requested by the Internet browser, and then the web server handles this request and delivers the requested data. If Varnish is activated for a site, it will cache the pages on the first visit and in case the user visits a cached page for a second time, the data will be delivered by the caching platform and not by the web server. The accelerated speed is an end result of the considerably faster response speed that Varnish offers compared to any server software. At the same time, this does not mean that the website visitors will keep being served the very same content again and again, as any change on any of the web pages is reflected in the content that Varnish stores in its system memory.
Varnish in Cloud Hosting
Varnish is available as an optional upgrade with all our Linux cloud hosting packages
. You can add it to your account from the Hepsia hosting Control Panel, which is available with all shared plans and you will get a pretty simple-to-use graphical interface, which will grant you complete control over the content caching platform. Using one-click fast-access controls, you can restart or shut down any of the instances, in other words – Varnish will no longer work for a certain website. You can also check an elaborate log file or erase the cache associated with any of the sites. When you add Varnish to your shared web hosting package, you will be able to select the total amount of system memory that will be at your disposal for caching purposes and the number of the websites that will use Varnish. You can always order more memory in increments of 32 MB and, for best performance, you can get a dedicated IP address for the websites that will use Varnish. This will enable you to take full advantage of your websites and to have lots of satisfied website visitors.
