Learn exactly what Varnish is. Get to know much more about web accelerators and their function.
Varnish is a web application accelerator, which has been gaining a lot of popularity in recent years, as it can increase the loading speed of any site, at times even by 100 percent, based on the content. This tool is sometimes referred to as a caching HTTP reverse proxy as well and is used to lower the overall load on the server and to increase the access speed for the website visitors. Each time a visitor accesses a page on a certain Internet site, the web browser request is handled by the web server and the requested information is sent as a response. If Varnish is activated, it caches the pages that the website visitor opens and if any of them is opened once again, it is delivered by Varnish and not by the web server directly. The performance increase comes from the fact that the accelerator handles the web requests tremendously quicker than any web server, which leads to much faster browsing speeds for the users. If any content is changed in the meantime, the cached webpages will also be ‘refreshed’ the next time somebody accesses them.
Varnish in Shared Hosting
You can use Varnish’s potential and boost your websites’ load speed irrespective of the shared hosting package that you have picked and you can add and set up the data caching platform with a few clicks from the intuitive GUI offered by our next-generation Hepsia hosting Control Panel. During the procedure, you’ll be able to choose two different things – how many sites will use the Varnish platform, i.e. the number of instances, and how much info will be cached, in other words – the amount of system memory. The latter is available in increments of 32 MB and is not linked to the number of instances, so you can use more instances and less memory and vice versa. If you’ve got plenty of content on a specific website and you receive many website visitors, more system memory will guarantee you better results. You may also consider using a dedicated IP address for the sites that will use the Varnish platform. Hepsia will provide you with simple 1-click buttons for turning off or restarting any instance, for erasing the cache associated with any site and for seeing comprehensive logs.
