From 157dd7be6904c59ce62d2ff404bc234eb2e32cbb Mon Sep 17 00:00:00 2001 From: Florian Forster Date: Thu, 28 Jul 2016 10:53:50 +0200 Subject: [PATCH] varnish plugin: Add informative warnings to the config handling. Not all config options are valid for all versions of Varnish. Rather than removing the if-clause altogether, which results in a "Ignoring unknown configuration option" warning, print a user-friendly warning instead.
