Learn exactly what Varnish is. Know more about web accelerators and their goal.
Varnish is a web application accelerator tool, which has been gaining a lot in popularity in recent years, as it can increase the speed of any website, at times even by 100 percent, depending on the content. This tool is occasionally referred to as a caching HTTP reverse proxy too and is used to lower the overall load on the physical machine and to improve the access speed for the site visitors. Every time a visitor loads a page on a certain Internet site, the browser request is taken care of by the web server and the requested info is returned as a response. If the Varnish accelerator is activated, it caches the web pages that the visitor opens and if any of them is loaded again, it is delivered by Varnish and not by the web server directly. The increase in the performance comes from the fact that the accelerator processes the web requests considerably faster than any web server, which leads to much faster browsing speeds for the visitors. If any data is updated in the meantime, the cached pages will also be ‘refreshed’ the next time someone opens them.
Varnish in Web Hosting
Our company offers Varnish as an optional upgrade with each and every Linux web hosting package
and if you’d like to use it, you can add it to your shared account through the Upgrades section in your Hepsia Control Panel. There’re two separate features that can be upgraded – the instances and the system memory. The first one pertains to the number of the websites that you’d like to employ Varnish for and the second one, which is offered in increments of 32 megabytes, shows the maximum amount of data that the data caching platform can store at any particular moment. Hepsia’s simple-to-use GUI will enable you to cancel or to restart any instance, to check comprehensive logs or to get rid of the platform’s cache with just one click. For best results, you can employ a dedicated IP address for the Internet sites that will use the caching platform. With Varnish, your site will open much faster, which means more pleased site users and potential clients.
