+	# The ServerName directive sets the request scheme, hostname and port that
+	# the server uses to identify itself. This is used when creating
+	# redirection URLs. In the context of virtual hosts, the ServerName
+	# specifies what hostname must appear in the request's Host: header to
+	# match this virtual host. For the default virtual host (this file) this
+	# value is not decisive as it is used as a last resort host regardless.
+	# However, you must set it for any further virtual host explicitly.
