+# The same content should never be available under two different
+# URLs, especially not with and without `www.` at the beginning.
+# This can cause SEO problems (duplicate content), and therefore,
+# you should choose one of the alternatives and redirect the other
+# one.
+#
+# By default `Option 1` (no `www.`) is activated.
+# http://no-www.org/faq.php?q=class_b
+#
+# If you would prefer to use `Option 2`, just comment out all the
+# lines from `Option 1` and uncomment the ones from `Option 2`.
+#
+# (!) NEVER USE BOTH RULES AT THE SAME TIME!
