Varnish is a web application accelerator tool, which has been gaining a lot in popularity lately, as it can increase the loading speed of any Internet site, at times even by one hundred percent, depending on the content. This tool is occasionally called a caching HTTP reverse proxy too and is used to decrease the overall server load and to accelerate the access speed for the website visitors. Each time a visitor loads a page on a particular Internet site, the web browser request is processed by the web server and the requested content is served as a response. If the Varnish accelerator is activated, it caches the web pages that the visitor browses and in case any of them is accessed once again, it’s delivered by Varnish and not by the web server directly. The performance improvement comes from the fact that the accelerator handles the web requests considerably quicker than any web server, which leads to much faster browsing speeds for the users. If any content is updated in the meantime, the cached web pages will also be updated the next time somebody attempts to open them.
