This section is about tuning the performance of your Varnish server,
and about tuning the performance of your website using Varnish.
+The section is split into two. One deals with the various tools and
+functions of Varnish that you should be aware of and the other focuses
+on the how to purge content out of your cache. Purging of content is
+essential in a performance context because it allows you to extend the
+*time-to-live* (TTL) of your cached objects. Having a long TTL allows
+Varnish to keep the content in cache longer, meaning Varnish will make
+send fewer requests to your relativly slow backend.
