#
# Based upon the NCSA server configuration files originally by Rob McCool.
#
# This is the main Apache server configuration file. It contains the
# Configuration directives that give the server its instructions.
# See For detailed information about
# the directives.
#
# do not simply read the instructions in here without understanding
# What they does. They ' re here is only as hints or reminders. If you are unsure
# Consult the online docs. You have been warned.
#
# The configuration directives is grouped into three basic sections:
# 1. Directives that control the operation of the Apache server process as a
# Whole (the ' Global Environment ').
# 2. Directives that define the parameters of the ' main ' or ' default ' server,
# which responds to requests this aren ' t handled by a virtual host.
# These directives also provide default values for the settings
# of all virtual hosts.
# 3. Settings for virtual hosts, which allow WEB requests to being sent to
# different IP addresses or hostnames and has them handled by the
# same Apache server process.
#
# 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 would use this explicit path. If the filenames do *not* begin
# with "/", the value of ServerRoot are prepended--so "logs/foo.log"
# with ServerRoot set to "C:/Program Files/apache group/apache2" would be interpreted by the
# server as "C:/Program Files/apache group/apache2/logs/foo.log".
#
# Note:where Filenames is specified, you must use forward slashes
# instead of backslashes (e.g, "c:/apache" instead of "C:\apache").
# If A drive letter are omitted, the drive on which Apache.exe is located
# would be used by default. It's recommended that's always supply
# Explicit drive letter in absolute paths, however, to avoid
# confusion.
#

# # # section 1:global Environment
#
# The directives in this section affect the overall operation of Apache,
# such as the number of concurrent requests it can handle or where it
# can find its configuration files.
#

#
# serverroot:the top of the directory tree under which the server ' s
# Configuration, error, and log files are kept.
#
# note! If you intend to place this on an NFS (or otherwise network)
# mounted FileSystem then please read the LockFile documentation (available
# at );
# You'll save yourself a lot of trouble.
