   7# Do NOT simply read the instructions in here without understanding   
   8  
   9# what they do. They're here only as hints or reminders. If you are unsure   
  10  
  11# consult the online docs. You have been warned.   
  12  
  13#   
  14  
  15# The configuration directives are grouped into three basic sections:   
  16  
  17# 1. Directives that control the operation of the Apache server process as a   
  18  
  19# whole (the 'global environment').   
  20  
  21# 2. Directives that define the parameters of the 'main' or 'default' server,   
  22  
  23# which responds to requests that aren't handled by a virtual host.   
  24  
  25# These directives also provide default values for the settings   
  26  
  27# of all virtual hosts.   
  28  
  29# 3. Settings for virtual hosts, which allow Web requests to be sent to   
  30  
  31# different IP addresses or hostnames and have them handled by the   
  32  
  33# same Apache server process.   
  34  
  35#   
  36  
  37# Configuration and logfile names: If the filenames you specify for many   
  38  
  39# of the server's control files begin with "/" (or "drive:/" for Win32), the   
  40  
  41# server will use that explicit path. If the filenames do *not* begin   
  42  
  43# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"   
  44  
  45# with ServerRoot set to "/etc/httpd" will be interpreted by the   
  46  
  47# server as "/etc/httpd/logs/foo.log".

  55#   
  56  
  57# The directives in this section affect the overall operation of Apache,   
  58  
  59# such as the number of concurrent requests it can handle or where it   
  60  
  61# can find its configuration files.
