2: ## httpd.conf -- Apache HTTP server configuration file
3: ##
4:
5: # This is the main server configuration file. See URL http://www.apache.org/
6: # for instructions.
7:
8: # Do NOT simply read the instructions in here without understanding
9: # what they do, if you are unsure consult the online docs. You have been
10: # warned.
11:
12: # Originally by Rob McCool
13:
14: # ServerType is either inetd, or standalone.
15:
16: ServerType standalone
17:
18: # If you are running from inetd, go to "ServerAdmin".
19:
20: # Port: The port the standalone listens to. For ports < 1023, you will
21: # need httpd to be run as root initially.
22:
23: Port 80
24:
25: # HostnameLookups: Log the names of clients or just their IP numbers
26: # e.g. www.apache.org (on) or 204.62.129.132 (off)
27: # The default is off because it'd be overall better for the net if people
28: # had to knowingly turn this feature on.
29:
30: HostnameLookups off
31:
32: # If you wish httpd to run as a different user or group, you must run
33: # httpd as root initially and it will switch.
34:
35: # User/Group: The name (or #number) of the user/group to run httpd as.
36: # On SCO (ODT 3) use User nouser and Group nogroup
37: # On HPUX you may not be able to use shared memory as nobody, and the
38: # suggested workaround is to create a user www and use that user.
39: # NOTE that some kernels refuse to setgid(Group) or semctl(IPC_SET)
40: # when the value of (unsigned)Group is above 60000;
41: # don't use Group nobody on these systems!
42:
1.4 ! harris41 43: User nobody

47: # e-mailed.

1.1 harris41 50:
51: # ServerRoot: The directory the server's config, error, and log files
52: # are kept in.
53: # NOTE! If you intend to place this on a NFS (or otherwise network)
54: # mounted filesystem then please read the LockFile documentation,
55: # you will save yourself a lot of trouble.

60: # is used to tell the server which IP address to listen to. It can either
61: # contain "*", an IP address, or a fully qualified Internet domain name.
62: # See also the VirtualHost directive.
63:

77: # Dynamic Shared Object (DSO) Support
78: #
79: # To be able to use the functionality of a module which was built as a DSO you
80: # have to place corresponding `LoadModule' lines at this location so the
81: # directives contained in it are actually available _before_ they are used.
82: # Please read the file README.DSO in the Apache 1.3 distribution for more
83: # details about the DSO mechanism and run `httpd -l' for the list of already
84: # built-in (statically linked and thus always available) modules in your httpd

213: # The LockFile directive sets the path to the lockfile used when Apache
214: # is compiled with either USE_FCNTL_SERIALIZED_ACCEPT or
215: # USE_FLOCK_SERIALIZED_ACCEPT. This directive should normally be left at
216: # its default value. The main reason for changing it is if the logs
217: # directory is NFS mounted, since the lockfile MUST BE STORED ON A LOCAL

235: # to the server the response is coming from) it will use ServerName and
236: # Port to form a "canonical" name. With this setting off, Apache will
237: # use the hostname:port that the client supplied, when possible. This
238: # also affects SERVER_NAME and SERVER_PORT in CGIs.

270: # handle the current load, plus a few spare servers to handle transient
271: # load spikes (e.g., multiple simultaneous requests from a single
272: # Netscape browser).
273:
274: # It does this by periodically checking how many servers are waiting
275: # for a request. If there are fewer than MinSpareServers, it creates
