The perfect Varnish configuration for WordPress, Joomla, Drupal & other (common) CMS based websites

Updated on December 15th, 2021

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 180 sec (3 minute) cache time for cacheable content that does not have the correct cache-control HTTP headers. You can safely increase this to 300 sec (or more) for less busier sites or drop it to 60 sec or even 30 sec for high traffic sites. It obviously depends on your use case.

In order to clone the TVN application from sourceforge to github I performed the following steps.

rsync -av rsync://tnv.cvs.sourceforge.net/cvsroot/tnv/* .
svn export --username=guest http://cvs2svn.tigris.org/svn/cvs2svn/trunk cvs2svn-trunk
cp ./cvs2svn-trunk/cvs2git-example.options ./cvs2git.options
vim cvs2git.options
cvs2svn-trunk/cvs2git --options=cvs2git.options --fallback-encoding utf-8
