The perfect Varnish configuration for Joomla, WordPress & other CMS based websites

IMPORTANT: Read this before implementing one of the configuration files below (for either Varnish 3.x or 4.x+).

USE: Replace the contents of the main Varnish configuration file located in /etc/varnish/default.vcl (root server access required - obviously) with the contents of the configuration you'll use (depending on your Varnish version) from the 2 examples provided below.

IMPORTANT: The following setup assumes a 2 minute cache time. You can safely increase this to 5 mins for less busier sites or drop it to 1 min or even 30s for high traffic sites.

This configuration requires an HTTP Header and a user cookie (see the Joomla section) to identify if a user is logged in a site, in order to bypass caching overall. If your CMS provides a way to add these 2 requirements, then you can use this configuration to speed up your site or entire server. You can even exclude the domains you don't want to cache if you're looking to use

    .host = "localhost";
    .port = "8080";
