Take a look at Varnish, learn more details on web accelerators and see exactly what is they do.
Varnish is a website accelerator platform, which caches info for the sake of quicker access. It’s occasionally referred to as a caching HTTP reverse proxy as well and it interacts between a web server and a web browser. When a website visitor opens a particular page, the content is requested by the web browser, and then the server processes this browser request and delivers the required content. If Varnish is activated for a particular site, it will cache the pages at the first request and if the visitor opens a cached page again, the info will be delivered by the accelerator platform and not by the server. The increased loading speed is an end result of the much faster response time that the Varnish platform offers as compared with any web server software. Of course, this doesn’t mean that the website visitors will keep being served the same content over and over again, as any change on any of the pages is reflected in the content that Varnish stores in its memory.
Varnish in Shared Web Hosting
If you host your sites under a shared web hosting account with our company, you’ll be able to add Varnish with several clicks of the mouse via your hosting Control Panel. The platform is offered as an upgrade with all our hosting plans and you can select the number of the websites that will use it and the maximum amount of system memory that will be used for the cached data. The two upgradeable features in the Control Panel’s Upgrades section are the amount of memory and the number of instances and they’re not directly tied to each other, so you can decide whether you want plenty of memory for one single large-size website or less memory for several smaller ones. You can unleash the full potential of the Varnish platform if the websites use a dedicated IP address. Using the Control Panel, you can easily start/reboot/cancel an instance, delete the cached contents independently for each website which uses Varnish or check an in-depth log file.
