+# This is the main Apache HTTP server configuration file.  It contains the

+# In particular, see
+# <URL:http://httpd.apache.org/docs/2.4/mod/directives.html>

+#
+# Do NOT simply read the instructions in here without understanding
+# what they do.  They're here only as hints or reminders.  If you are unsure
+# consult the online docs. You have been warned.
+#
+# Configuration and logfile names: If the filenames you specify for many
+# of the server's control files begin with "/" (or "drive:/" for Win32), the
+# server will use that explicit path.  If the filenames do *not* begin
+# with "/", the value of ServerRoot is prepended -- so "logs/access_log"
+# with ServerRoot set to "/usr/local/apache2" will be interpreted by the
+# server as "/usr/local/apache2/logs/access_log", whereas "/logs/access_log"
+# will be interpreted as '/logs/access_log'.

+# Listen: Allows you to bind Apache to specific IP addresses and/or
