It contains the 3 | # configuration directives that give the server its instructions. 4 | # See for detailed information. 5 | # In particular, see 6 | # 7 | # for a discussion of each configuration directive. 8 | # 9 | # 10 | # Do NOT simply read the instructions in here without understanding 11 | # what they do. They're here only as hints or reminders. If you are unsure 12 | # consult the online docs. You have been warned. 13 | # 14 | # The configuration directives are grouped into three basic sections: 15 | # 1. Directives that control the operation of the Apache server process as a 16 | # whole (the 'global environment'). 17 | # 2. Directives that define the parameters of the 'main' or 'default' server, 18 | # which responds to requests that aren't handled by a virtual host. 19 | # These directives also provide default values for the settings 20 | # of all virtual hosts. 21 | # 3. Settings for virtual hosts, which allow Web requests to be sent to 22 | # different IP addresses or hostnames and have them handled by the 23 | # same Apache server process. 24 | # 25 | # Configuration and logfile names: If the filenames you specify for many 26 | # of the server's control files begin with "/" (or "drive:/" for Win32), the 27 | # server will use that explicit path. If the filenames do *not* begin 28 | # with "/", the value of ServerRoot is prepended -- so "logs/foo.log" 29 | # with ServerRoot set to "/etc/httpd" will be interpreted by the 30 | # server as "/etc/httpd/logs/foo.log". 31 | # 32 | 33 | ### Section 1: Global Environment 34 | # 35 | # The directives in this section affect the overall operation of Apache, 36 | # such as the number of concurrent requests it can handle or where it 37 | # can find its configuration files. 38 | # 39 | 40 | # 41 | # Don't give away too much information about all the subcomponents 42 | # we are running.
