Varnish is a web app accelerator tool, which has been gaining a lot of popularity lately, as it can increase the load speed of any Internet site, at times even by 100%, based on the content. This tool is occasionally referred to as an HTTP reverse proxy as well and is used to lower the overall load on the server and to enhance the access speed for the site visitors. Each time a visitor accesses a page on a certain Internet site, the web browser request is taken care of by the web server and the requested information is delivered as a response. If Varnish is activated, it caches the pages that the visitor opens and if any of them is accessed once more, it is fetched by Varnish and not by the server directly. The increase in the overall performance is due to the fact that the accelerator processes the browser requests tremendously quicker than any web server, which results in much faster browsing speeds for the website visitors. If any content is updated meanwhile, the cached web pages will also be updated the next time someone accesses them.
Varnish in Shared Website Hosting
Varnish is offered as an optional upgrade with all our Linux shared website hosting packages. You can add it to your account from the Hepsia Control Panel, which comes with all shared web hosting plans and you will get a truly user-friendly interface, which will give you complete control over the content caching system. Using one-click fast-access controls, you can reboot or terminate any of the instances, i.e. Varnish will no longer be enabled for a certain website. You can also check an elaborate log or erase the cache for any of the sites. When you add Varnish to your shared web hosting package, you’ll be able to choose the maximum amount of memory that will be at your disposal for caching purposes and the number of the sites that will use Varnish. You can always order more memory in increments of 32 MB and, for best performance, you can allocate a dedicated IP address to the sites that will use Varnish. This will allow you to get the most out of your sites and to have a lot of satisfied site users.
